Atomicity of rename on NFS
by Edward Rolison 03 Jan '17

03 Jan '17

Hello fellow NetApp Admins. I have a bit of an odd one that I'm trying to troubleshoot - and whilst I'm not sure it's specifically filer related, it's NFS related (and is happening on a filer mount). What happens is this - there's a process that updates a file, and relies on 'rename()' being atomic- a journal is updated, and then reference pointer (file) is newly created, and renamed over an old one. The expectation is that this file will always be there - because "rename()" is defined as an atomic operation. But that's not quite what I'm getting - I have one nfs client doing it's (atomic) rename. And another client (different NFS host) reading it, and - occasionally - reporting 'no such file or directory'. This is causing an operation to fail, which in turn means that someone has to intervene in the process. This operation (and multiple extremely similar ones) happen at 5m intervals, and every few days (once a week maybe?) it fails for this reason, and our developers think that should be impossible. But as such - it looks like a pretty narrow race condition. So what I'm trying to figure out is first off: - Could this be a NetApp bug? We've moved from 7 mode to CDOT, and it didn't happen before. On the flip side though - I have no guarantee that it 'never happened before' because we weren't catching a race condition. (moving to new tin and improving performance does increase race condition likelihood after all) - Could this be a kernel bug? We're all on kernel 2.6.32-504.12.2.el6.x86_64 - and whilst we're deploying Centos 7, all the hosts involved aren't yet. (But that's potentially also just coincidence, as there's quite a few hosts, and they're all the same kernel versions). - Is it actually impossible for a file A renamed over file B to generate ENOENT on a different client? Specifically, in RFC3530 We have: " The RENAME operation must be atomic to the client.". So the client doing the rename sees an atomic operation - but the expectation is that a separate client will also perceive an 'atomic' change - once the cache is refreshed, the 'new' directory has the new files, and at no point was there 'no such file or directory' because it was either the old one, or the newly renamed one. Is this actually a valid thing to think? This is a bit of a complicated one, and has me clutching at straws a bit - I can't reliably reproduce it - a basic fast spinning loop script on multiple client to read-write-rename didn't hit it. I've got pcaps running hoping to catch it 'in flight' - but haven't yet managed to catch it happening. But any suggestions would be gratefully received.

SOLVED: snapmirror source and target aggregate usage don't match?
by Rue, Randy 23 Dec '16

23 Dec '16

Hello All, This provided an opportunity to find and implement some improvements in our dedupe/snapmirror configuration but that wasn't the real problem. We disabled dedupe on all but the two SVMs that were showing space savings of >10% or a couple of hundred GB, and changed the dedupe schedule to run hourly and with ample time to finish before the hourly snapmirror schedule. The real problem turned out to be that while we configure all our data volumes on the source cluster as thin provisioned, when DOT creates the target volume on the secondary "thick." And as the Storage Efficiency settings aren't exposed anywhere in the GUI on the secondary cluster for those volumes, it took some digging and five people staring at the CLI output before we figured this out. We changed all the target volumes to thin and will check/change new ones as they're created Life is good.

Thank you for a NA docs pointer from a list member and the opportunity for a little RTFM before I reply to the list! Looks like my colleague's recollection of earlier versions still applies to 8.3. Essentially, we've been snapmirroring un-deduped data. My next question is, is it realistic to run dedupes hourly on 30-40 volumes totalling ~100TB? Because that's a much easier proposition than amending our SLAs to lengthen our snapshot cycles. And to get both on the same cycle, is it possible to make snapshots dependent on dedupe finishing, or do we just assume dedupe will complete, and if so, if it doesn't, what are the consequences? For example, if a dedupe that usually finishes at 5 minutes after the hour isn't done, and snapmirror runs then, will snapmirror then be syncing a full hour of full-sized changes? Last question for now: assuming both are on the same schedule, how do I get the current lost space back? Will it be reclaimed when the schedules are synced and the snapshots have rolled off? Or do I need to destroy and recreate the target volumes? Hope to hear from you, especially from any other shop running both snapmirror and dedupe.

To: <toasters(a)teaparty.net<mailto:toasters@teaparty.net>> Hello All, We run two 8.3 filers with a list of vservers and their associated volumes, with each volume snapmirrored (volume level) from the active primary cluster to matching vserver/volumes on the passive secondary. Both clusters have a similar set of aggregates of just about equal size. Both clusters' aggregates contain the same list of volumes of the same size, with the same space total/used/available on both sets. But on the target cluster the same aggregates are reporting 30% more used space. This is about on par with the dedupe savings we're getting on the primary so when I first noticed this my thought was to check that dedupe was OK on the target. But if you look in the webUI, it reports that no "storage efficiency" is available on a replication target, and ended up thinking this meant that the secondary data would have to be full-sized. I even recall asking someone and having this confirmed, but can't recall if that came from the vendor SE or our VAR SE or a support tech or. Now we're approaching the space limit of the secondary cluster and I'm looking deeper. At this point, as it appears that for each volume the total/used/free space matches after dedupe on the source, I'm thinking that dedupe properties aren't exposed on the target but the data is still a true copy of the deduped original. This is supported by being able to view dedupe stats on the target via the CLI that show the same savings as on the source. Note that we're also snapshotting these volumes, and while we're deduping daily, we're snapshotting hourly. A colleague mentioned remembering that this could mean mirrored data that's not deduped yet is being replicated full-size. But if so, wouldn't this be reflected in the dedupe stats on the target? OK, just found that "storage aggregate show -fields usedsize,physical-used" on the primary/source cluster shows that used and physical-used are about identical for all aggrs. On the secondary/target, used is consistently larger than physical-used and the total difference makes up the 30% I'm "missing." Is this a problem with my reporting? Are we actually OK and I need to look at physical-used instead of used? Or if we're not OK, where is the space being used and can I get it back? Thanks in advance for your guidance... Randy

Flash Cache vs Flash Pool
by Ehrenwald, Ian 21 Dec '16

21 Dec '16

Hello Toasters I'm thinking about if/how to implement Flash Pool in our new cDOT clusters, and was wondering if anyone could provide a bit of real world guidance for me. We have two SAS aggregates, aggr_sas_600g_c1n1 with 8x24 600g and aggr_sas_1200g_c1n1 with 4x24 1.2t. I've been doing a bunch of reading about Flash Pool vs Flash Cache and am trying to better understand their strengths and weaknesses. Flash Pool accelerates writes as well as reads (Flash Cache is reads only), however with Flash Pool there seems to be the potential for slower cache access/throughput vs Flash Cache since the data needs to travel the SAS path vs Flash Cache which is probably DMA through PCIe. Maybe that's not a concern at all, I don't know. Additionally, it appears that using Flash Pool disables the Flash Cache functionality for the aggregates which are in hybrid mode (makes sense), but then we have expensive add-in cards doing nothing. Our theoretical Flash Pool would be 2x24 200g, giving us about 5.5t of usable caching space to sprinkle into these aggregates. I've been running AWA on the cluster against those two SAS aggregates for ~24 hours and have come up with these stats: ### FP AWA Stats ### Host mrk_c1n1 Memory 61054 MB ONTAP Version NetApp Release 8.3.2P5: Tue Aug 23 01:27:00 PDT 2016 Basic Information Aggregate aggr_sas_600g_c1n1 Current-time Tue Nov 22 17:06:53 EST 2016 Start-time Mon Nov 21 12:48:17 EST 2016 Total runtime (sec) 101918 Interval length (sec) 600 Total intervals 157 In-core Intervals 1024 Summary of the past 157 intervals max ------------ Read Throughput (MB/s): 339.039 Write Throughput (MB/s): 123.536 Cacheable Read (%): 56 Cacheable Write (%): 66 Max Projected Cache Size (GiB): 787.463 Summary Cache Hit Rate vs. Cache Size Referenced Cache Size (GiB): 714.650 Referenced Interval: ID 132 starting at Tue Nov 22 12:33:05 EST 2016 Size 20% 40% 60% 80% 100% Read Hit (%) 25 30 30 30 33 Write Hit (%) 1 2 2 2 2 The entire results and output of Automated Workload Analyzer (AWA) are estimates.

The volumes in that aggregate are pretty much exclusively Oracle databases. The other aggregate, aggr_sas_1200g_c1n1, doesn't seem hit as hard. Given those statistics, what would you do if your options were ~5.5t of Flash Pool vs buying another 2t Flash Cache card per node in this HA pair? I seem to be missing the 'Projected Read Offload' and 'Projected Write Offload' statistics which would have been very useful, mentioned at the Flash Pool documentation in https://library.netapp.com/ecmdocs/ECMP1368404/html/GUID-2C3EC0DF-FEFE-4871 -A161-4A3BAC87DB69.html Thanks for any insight you all can provide. -- Ian Ehrenwald Senior Infrastructure Engineer Hachette Book Group, Inc. 1.617.263.1948 / ian.ehrenwald(a)hbgusa.com This may contain confidential material.

Re: snapmirror source and target aggregate usage don't match?

Maybe also review the dedup savings you are acheveing and consider disabling it on volumes getting 10% savings or so or less since the metadata required for dedup is something like 7%. On Dec 17, 2016 9:23 PM, "tmac" <tmacmd(a)gmail.com> wrote: Trial by fire? You will likely need to get a rough baseline of how long a single dedupe run takes on a source volume. Then look at doing multiple volumes and see how much the process slows down. With Spinnng media, the dedupe process can take a while on larger volumes. You may need to get a little creative and group some of the volumes together and created schedules for the deduping to happen at specific times. I really doubt you are going to be able to dedupe 30-40 volumes totalling ~100TB every hour. You should probably stagger and run throughout the day with different schedules you can create custom vol eff. policies that only run for a certain duration ("-" is default for no duration or up to 999 hours (whole numbers in hours)) and the qos-policy (for vol eff operations!) can be set to background (run, but do not impede) or best-effort (may slightly impact operations) as far as the timing, you may want to look at scripting with powershell or the NetApp SDK. Wait for a vol eff operation to finish, then do snapshots and/or mirroring. We could spend lots of time on this. I hope this helps at least a little. --tmac *Tim McCarthy, **Principal Consultant* *Proud Member of the #NetAppATeam <https://twitter.com/NetAppATeam>* *I Blog at TMACsRack <https://tmacsrack.wordpress.com/>* On Sat, Dec 17, 2016 at 2:13 PM, Rue, Randy <rrue(a)fredhutch.org> wrote: > Thank you for a NA docs pointer from a list member and the opportunity for > a little RTFM before I reply to the list! > > Looks like my colleague’s recollection of earlier versions still applies > to 8.3.

Regarding the FAS2240 I mentioned in my initial e-mail: SP netapp1*> system fru led show 0 FRU LED ID 0 is off SP netapp1*> system fru led show 1 FRU LED ID 1 is on I did google a bit for this symptom and therefore updated the SP firmware to the latest compatible one for my ontap version (2.1.3P2), but that did not fix the issue. Any fix for this symptom except for halting both nodes?

That will turn on the fault led if it's not enabled. What does "storage show fault" say? Other than that, the fault light could be on due to a previous fault in the system that has been cleared. Are you aware of any previous faults? If you log in to the Service Processor you can run "priv set diag", followed by "system fru led show". That command will list out the available fru's that you can check the status on. For example: SP nodeA*> system fru led show Invalid command usage Usage: system fru led show <FRU-LED-ID> Display status of the specified <FRU-LED-ID>. <FRU-LED-ID>: 0 = SP Controller Fault LED 1 = SP Heartbeat LED 2 = SP System Fault LED 3 = SP Fan 1 Fault LED 4 = SP Fan 2 Fault LED 5 = SP Fan 3 Fault LED 6 = SP IOXM Fault LED all others are not valid SP nodeA*> system fru led show 2 FRU LED ID 2 is off You can check the status of each fru id to see which one is on. From there double check there aren't any actual faults with that component. Still no faults? You may just be able to turn off the led using the "system fru led set" command.

qtree snapmirror inexplicably slow once a week
by BERNTSEN Basil 14 Dec '16

14 Dec '16

Hi folks, I'm at a loss. I have an unmaintained (fas2020) 7-mode HA pair in a site that's slated to be decommed, but for now, I need to keep the lights on. There is a qtree snapmirror that, aside from Mondays, runs in about 3-4 hours. Mondays, it takes 2-4 days. The change rate on the source doesn't appear to be any different. Also, this was working happily for years and only started acting up lately. There are only 5 disks on the system, and while they're at 100% now, they're also at 100% during a sample taken while this context wasn't updating, and while it was updating in a way that finished in 4 hours. So far, I've checked statit during the event and while idle, and I couldn't see anything that stuck out as a massive difference, except maybe name cache hits? I have 68% name cache hits during this transfer, and 100% while idle. I don't see anything suspicious in the wafl scan status, and reallocate status -v shows: Reallocation scans are on No reallocation status. CPU is idle, network has no errors. Does anyone have any suggestions? What kinds of things should I be looking at?

"statistics aggregate show"
by Edward Rolison 13 Dec '16

13 Dec '16

I have been running (on CDOT 8.3): statistics aggregate show statistics volume show over ssh, via cron, and graphing them. Since updating to 8.3.2P6, I've now got a different error: Error: command failed: More than 50 samples are not allowed. Please delete existing sample(s) to create a new sample. Now, that's not a deprecation warning, but I'm wondering if the functionality has been disabled anyway. Or if there's a workaround that any of you fine folk have seen. Or - for that matter - what's the neatest way to grab some summary statistics suitable for graphing at 5m intervals. (I can probably hack something together using the API, but haven't really needed to until now) Thanks and regards, Ed.
