Do I need a strong background in security program management to handle ASIS-CPP exam?
by paulinaturquoise＠sharebot.net 16 Apr '26

16 Apr '26

I’ve recently started preparing for the ASIS-CPP certification and I’m trying to understand how much prior experience I really need. Do I need a strong background in security program management to handle the ASIS-CPP exam effectively, or can I build that understanding during preparation? I’ve been going through some resources from Pass4Future and also reviewing ASIS-CPP Exam Questions, which helped me get a basic idea, but I still feel unsure about the depth of practical knowledge expected in real exam scenarios. Would appreciate insights from those who have already taken the exam or are currently preparing. Visit here For Free Practice Questions: https://www.pass4future.com/questions/asis/asis-cpp

Looking for Reliable Help to Buy, Sell, or Rent Property in Dubai?
by AHMAD Zeshan 06 Dec '25

06 Dec '25

I’ve been exploring the Dubai real estate market lately — both for investment and personal use — and wanted to share something useful for anyone who’s currently buying, selling, or renting here. I recently interacted with a real estate team that really stood out in terms of clarity, responsiveness, and how they break down market data. Instead of pushing random listings, they actually guide you based on budget, ROI, and location goals. Whether you're looking for a rental in a mid-range community or planning to buy into one of the new luxury villa projects, they keep the entire process transparent. They also handle selling quite efficiently — proper listing presentation, real market pricing, and serious buyers instead of just traffic. What I liked most was their follow-through; they don’t disappear once the viewing is done. If anyone here is navigating Dubai’s property market and needs support with buying, selling, or renting, I’d definitely recommend giving them a look. Happy to share more details if anyone needs guidance or wants to discuss specific areas. Website : https://maeqularealestate.com/

How UAE Residents Can Apply for a Visit Visa Easily
by premiertravelerandtours＠gmail.com 04 Dec '25

04 Dec '25

Hey everyone! If you are living in the UAE and planning to travel abroad, getting a visit visa is the first step. Many people get confused about the process, so I thought I’d share some tips based on my experience. For UAE residents, whether you are from Dubai, Abu Dhabi, or anywhere in the Emirates, you usually need a valid residency visa to apply for a visit visa to other countries. The good news is, the process is quite straightforward if you know the steps. Here’s a simple guide: Check the visa type – Are you traveling for tourism, business, or visiting family? This decides the documents you need. Prepare documents – Passport, UAE residency proof, completed application form, flight tickets, hotel bookings, and bank statements are usually required. Submit your application – Many countries now have online submission or centers like VFS Global in UAE. Pay the fees – Fees vary depending on the country and visa type. Wait for processing – It can take from a few days to a couple of weeks depending on the destination. Pro Tips: Always double-check your documents before submission. Make sure your passport has at least 6 months validity. A detailed travel itinerary improves your chances of approval. I personally used this method when applying for a Japan visit visa from Dubai, and everything went smoothly. If you’re planning your next trip, make sure to follow these steps and stay organized. Does anyone else have tips or recent experiences applying for visit visas from the UAE? Share your insights!

You can modify the nfs server: [-tcp-max-xfer-size <integer>] - TCP Maximum Transfer Size (bytes) (privilege: advanced) This optional parameter specifies the maximum transfer size (in bytes) that the storage system negotiates with the client for TCP transport of data for NFSv3 and NFSv4.x protocols. The range is 8192 to 1048576 Setting to the max of 1048576 will allow the client to be set to the same If your nfs client supports it, you can use “nconnect” set to 4 to also help Sent from Gmail Mobile.

Proxmox and NetApp NFS volumes
by Florian Schmid 07 Nov '25

07 Nov '25

Hello, we are moving to Proxmox now and I would need some help from you. In the past, I have always used NFSv3, because in our KVM environment, we had issues with NFSv4.1 and head fail-overs -> VMs got paused I think also VMware had such issues. Problem I think is that NFSv4.1 is stateful and on a head fail-over, this state got lost. I'm on 9.14.1. As NFSv3 is quite old and Proxmox is using a newer kernel, I wanted to ask, if someone of you have experience with Proxmox and NFS volumes from NetApp. Do you use special mount options? Is NFSv4.2 working fine with head fail-overs -> VMs are not pausing or don't even notice it? We have 25 Gbit network interfaces as a bond to our NetApp, are here any special options to configure? Are you using on VM disks "cache=none" or something different? Unfortunately, Proxmox has not much experience with NetApp either, so that I hope someone from you can help me here to create a good, fast and stable setup. This is how a mount point looks like with default options from Proxmox and NFSv3: nfs-root-01:/pve_DC_nfs_root_01 /mnt/pve/nfs-v3-root-01 nfs rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=172.16.4.3,mountvers=3,mountport=635,mountproto=udp,local_lock=none,addr=172.16.4.3 0 0 This is from our old virtualization oVirt: nfs-root-01:/oVirt_DC_nfs_root_01 /rhev/data-center/mnt/nfs-root-01:_oVirt__DC__nfs__root__01 nfs rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,soft,nolock,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=172.16.4.3,mountvers=3,mountport=635,mountproto=udp,local_lock=all,addr=172.16.4.3 0 0 * oVirt was using soft, but this I think, I shouldn't use on Proxmox and instead use hard. oVirt had a special watchdog for this. Best regards, Florian

Weird mass delete of files in a volume with ONTAP ASYNC-Delete
by Paul Letta 15 Jul '25

15 Jul '25

Hi Toasters. I'm running 9.14.1P13. I used the ONTAP ASYNC-Delete feature from the GUI (storage - Volumes - click on a volume - Click on File system - click on Explorer) to delete a few top level folders in a volume. That worked fine. I saw the background job running and they finished fine. I needed to delete much more. So I clicked on the trash can for one of the folders, clicked ok to start the delete. Then I clicked elsewhere in the GUI and clicked back to File-System, Explorer - and clicked on the trash can for a different folder. I did this maybe 6 or 7 times. When I check the jobs in ONTAP, I saw them all running. But then as I waited, I saw a lot more space being used by snapshots (via the df command) than the 6 or 7 folders I wanted to delete. At this point, only 1 ASYNC-Delete job was still running, so I canceled it. When I look at the live file system.. I see almost all folders (not just the 6 or 7 I clicked) have massive files deleted. Luckily for me, this volume was just a filesystem that barely changes.. so I could snapshot restore from a few hours before, and all was well. Now I'm scared to death of that file-explore page in the ONTAP GUI. I am the only administrator, so no one else could have been logged on to ONTAP. The pattern of deleted files makes a delete coming from a CIFS client very unlikely. There is no NFS export to this volume. Maybe the file explorer delete button was not intended for multiple, simultaneous runs? I don't know.. I know I will avoid page like a plague forever now. Any thoughts ? Thanks!

Large Amount of Aggregate Metadata
by Stephen Stocke 01 May '25

01 May '25

Hi All We have a couple AFF-A250 cluster running 9.15.1P7 which host NFS data stores for vSphere. Most of the volumes on this particular cluster are SnapMirror destination volumes at our secondary data center. When running 'df -A' to check the data distribution on the cluster, I noticed that one aggregate was showing 100% utilisation. Running 'storage aggregate show-space' indicates that 72% of the space (32TB!) is being consumed by aggregate metadata. What might cause so much metadata in the aggregate? Are there any commands to see which volume the metadata is associated with? Also, when logging on to the web console, there was no indication of a problem or unhealthy node so I'm not sure if the aggregate was actually full. I ran a vol move to the partner data aggregate successfully so I now have a bit of free space. (There is also a question as to why our monitoring system wasn't reporting any issues... but if system manager doesn't report an issue...?) Thanks, Steve

Igfrp IP Distribution Function

Greetings fellow toaster admins I hope someone can shed some light on the IP distribution function for lacp ifgrps. We have a four port, multi mode lacp ifgrp, a0a, using interfaces e2a-e2d. We observe SnapMirror traffic egressing port e2c. The XOR of the last two bits of the source and destination IPs are either x0 or x3 so I am expecting traffic to egress either the first or fourth port in the ifgrp. Assuming e2a is port 0, e2b is port 1, etc., I would expect traffic to egress either e2a (0x0) or e2d (0x3). What am I missing? I can’t find any details about the actual hashing function for IP distribution or port member indexing in an ifgrp to confirm my assumptions. Both clusters are a single A250 HA pair running 9.15.1. I’m typing this with my thumbs so apologies for any typos or insufficient detail. Best wishes Stephen

Unable to schedule service processor update
by Alexander Griesser 14 Jan '25

14 Jan '25

Hey folks, I got a bunch of A220s here which I want to update to the latest SP firmware: CLUSTER::*> system service-processor show IP Firmware Node Type Status Configured Version IP Address ------------- ---- ----------- ------------ --------- ------------------------- Node1 BMC online true 11.9P1 127.0.0.1 Node2 BMC online true 11.9P1 127.0.0.2 2 entries were displayed. But everytime I try to install the update from the Ontap prompt, I get the following message: CLUSTER::*> system service-processor image update -node * -package SP_FW_308-04195_11.11.tar.gz Note: Firmware update will need to reboot the SP on completion. If your console connection is through the SP, it will be disconnected Do you want to proceed with the firmware update ? {y|n}: y Error: command failed on node "Node1": Unable to schedule Service Processor update. The only KB article I found for this issue is this one: https://kb.netapp.com/on-prem/ontap/OHW/OHW-KBs/BMC_upgrade_fails_with_Erro… I can verify that the file is not corrupted (compared the MD5 sums) and I tried to reboot the SP before the update, but all to no avail. The only way I can get the BMC firmware update installed is by using "bmc update -f" directly on the bmc shell, but that's harder to automate. Has anyone ever stumbled upon that and has an idea? SP Auto Updates are enabled, but they're not starting either - waited for a day for them to do their job.

This mailing list, like a number of others, is hosted on my colocated box, using mailman2. The box is running CentOS 7, which goes end-of-life fairly soon, and I plan to rebuild it running Debian 12 some time in the next month or two (more solid notice will be given nearer the time!). There have been no posts to this list since Oct 2023, so although we still have a goodly number of subscribers, I wonder whether, after 26 years, the list has run its course. I have enough other lists that I'll still have to put mailman3 on the new box, but migrating a large list with a big archive from mailman2 to mailman3 is still quite an undertaking. If it turned out that it was pointless, it would be a large enough job that not having to do it would be a noticeable time-saver. Let me clarify that I'm not looking to offload the list, or to move it again. If it's still useful, I'll do the legwork and migrate it; if it's not, then let's just turn it off. So I seek guidance. Let's not have the discussion on-list, but if you have any thoughts about whether this list is still useful, please let me know privately. Both positive and negative thoughts are valuable, so if you have any strong feelings either way, I'd like to hear them. Thanks! -- Tom Yates - https://www.teaparty.net

Re: Question about flash pool maximum SSD size and local tiering

So you're thinking to have several different "physical tiers" with different characteristics (performance, inherent latency) for different workloads -- in the same HA-pair? Several different Aggrs with differing performance and behaviour in the same node, FAS8300? (it's a fairly powerful machine so it can do this adequately in many smaller workload cases). Or do you mean in different 8300 nodes in a X-node cluster (what's X?) This idea is much harder to make successful than you probably think. It requires you to know very much about your workloads, your applications, what they do so that you can place the correct data in the right place and you have to have the ability to do this over time as data volumes grow. Assuming they do... It's very hard indeed to automate so you need people who can baby watch this continuously and move data around. Yes that's mostly non-disruptive, but it's still quite a lot of work. It also pretty much assumes for it to be successful in the longer run that your applications do not change their workload patterns and/or pressure more than very slowly. Is this the case? All in all FabricPool is much much more automatic. It just does the job itself, pretty much w/o fuss once you've tuned it a bit w.r.t. cool down period(s) and things. It "just works". You do need an S3 target system, but as has already been pointed out it can be ONTAP with NL-SAS drives, if you already have a bunch of these lying about you can repurpose those and instead use new Cx00 (or Ax00) nodes in the "front end". The challenge with FabricPool is the network: the connection between the front end and the S3 back end needs to be very good and solid. You have to understand it fully and know every detail how it's built so you know you can trust it's capacity and latency; traffic can be quite bursty. I'm not very positive to your idea here I'm afraid: "Not all SSDs will be used for flash-pool, only some for cache and the rest for fast SSD storage." it's just my (long) experience of this that it's not very productive in reality and it costs a lot of operations (manual work, skilled personnel). It also tends to give you various problems when you need to do HW LCM (upgrade your controllers and disk back ends). It inevitably leads to stranded capacity in more than once dimension as time passes. /M -- Sr Human ;-) Alt: r.m.bergman(a)gmail-DEL_THIS-.com -- "Qui vicit non est victor nisi victus fatetur." - Ennius

Hi Florian, If you have the NL-SAS aggregate in place already I’d recommend having a look at using AWA to figure out what the optimal cache size would be: https://docs.netapp.com/us-en/ontap/disks-aggregates/determine-flash-pool-c… That would give you an idea of how much Flash Pool capacity you’d really benefit from. Regarding 3.8TB vs 7.6 TB – if the 7.6 TB drives are not listed as supported in the HWU, it’s most likely not supported. There’s also a note in the HWU for the 3.8TB drives under “System Cache Limits” – “Max number of Flash Pool Data SSDs: 20” (this is excluding RAID parity & hot spares) – if I’m intepreting that note correcly there’d be no point in adding more than one shelf of 3.8TB drives.

We don't know, if we should take 2 shelves with 3.8 TB or 1 shelf with 7.6 TB. I tend to one shelf with 7.6 TB... We are using flash-pool already with Raid-4, exactly for saving space. My problem is now, that I'm concerned about the HWU statement, that there is no SSD listed for using in flash-pool over 3.8 TB. This let me think, that flash-pool is not supported for SSD with 7.6 TB or greater. I haven't found anything else about it on NetApp site, only in the HWU for system cache limits for FAS 8300 Same limits are also for 8700 or 9000 series, no difference here. Really strange.

FlashPool SSDs (unlike FlashCache) are attached to aggregates as normal RAID groups, so you can use as many 3.8 TB drives in RAID-DP as you like to hit the maximum FlashPool capacity. Note that FlashPool and FabricPool use the same underlying tiering metadata structures, so you can only have one or the other enabled on any given aggregate.
