Symantec AV not releasing pBlks
by Horton, Jamie 18 May '07

18 May '07

Anyone ever had the below issue?: I'm running 2 Win2k3 servers as my Symantec Scan Engine Servers (running Symantec Anti-Virus for Network Attached Storage 4.3). Both act as primary vscan scanners (for my R200 and FAS960 filers). Every once in awhile one or both of my filers stop servicing CIFS requests, because they run out of pBlks (control blocks). After several outages this week, I have learned that in order for everything to run clean, I have to do the following in sequence: 1. vscan off (on both filers) 2. Stop scan engine service on both win2k3 servers 3. vscan on (on both filers) 4. Start scan engine service on both win2k3 servers If I have everything on, and I stop and start vscan only on the filers (without recycling services on the win2k3 servers), I immediately start losing pBlks until they are all exhausted, then nobody can access any shares. NetApp suggested I upgrade to 7.2.2 since this version deals with pBlks better. I upgraded last night, and since I didn't recycle scan engine services on the win2k3 servers, I ran out of pBlks early this morning. Once I executed the sequence above, all was well. NOTE: we are continuing to add more users to our environment (user home drives are on the FAS960), which obviously add more to the scanning load, but that doesn't account for it happening on my R200 (software shares and application shares). Any information would be greatly appreciated. Thanks, -Jamie

RE: Off Topic - brocade monitoring

Hi Blake, You should use TX and RX FC Words. Note that these values HAS TO be multiplied by four to recieve number of bytes! OIDs: TX FC Words: 1.3.6.1.4.1.1588.2.1.1.1.6.2.1.11.(port+1) RX FC Words: 1.3.6.1.4.1.1588.2.1.1.1.6.2.1.12.(port+1) SNMP starts port count at 1, not at 0. So, for switch port 0 you should use 1.3.6.1.4.1.1588.2.1.1.1.6.2.1.11.1 and 1.3.6.1.4.1.1588.2.1.1.1.6.2.1.12.0 Finally, note that (RxWord + TxWord * 4) give the same results as PortPerfShow. More info on http://www.brocadeconnect.com (you need a user/pass).

offline ldap impacting cifs
by jay d 14 May '07

14 May '07

I have 2 clustered filers. One filer shares several vols via nfs. The security on these vols is set to unix. Some of them require access from windows in which case a cifs share has been created and ldap is used to map windows accounts to unix uids/gids. On the other filer, all vols are ntfs, there's no nfs (cifs only), and ldap is configured and enabled. We experienced an outage on all cifs connections on both filers when the one ldap server we were using went down. "net view" (from a windows client) would hang and explorer couldn't find the network path. I would expect the mapping to fail and windows users to be mapped to the default pcuser on the unix vols accessed via cifs. I would also expect the cifs only filer to have no issues continuing to serve cifs. Is my expectation off? I can resolve the issue by adding additional ldap hosts but I want to uncover why cifs only connections are dependent on ldap when my ad domain controllers are online. Thanks, jd

Problems with mixed mode
by Michael Fahy 14 May '07

14 May '07

We have an FAS960 running NFS and CIFS. There are entries in the cifs_homedir.cfg file so that Windows users can map drives to their Unix home directories. Windows users can successfully map drives to their unix home directories but unless their files and directories are configured with write permission for "everyone", (i.e. 666 permissions for files) the Windows users cannot write to their own files and directories. The filer is not successfully matching the Windows username with the corresponding Unix username (even though the names are the same). We are using OpenLDAP for authentication on the Unix side. We have been told that "Files and directories created from unix using nfs only get their permissions read properly by other unix systems, and the same with cifs by Windows systems" but I do not believe this. I'm sure we are just not configuring the filer correctly. Any suggestions?

RE: Duplicate nonboot vol0
by MCLACHLAN, Alan 11 May '07

11 May '07

I have had this occur a couple of times over the years. Note in Michael's case the two vol0's were on the same physical disks, so it wasn't a result of drive adds. If you search on NOW I think from memery there's a bug article in about a race condition where this can occur. I'm too busy to bother looking it up right now ;) Regards, Alan McLachlan Technical Analyst Information Management Services Department of Education, Training and the Arts (DETA) Floor 11 Education House, 30 Mary Street, Brisbane Fax: 07 3237 9695 Mob: 0429 655644 -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Dave Rubright Sent: Friday, May 11, 2007 10:41 AM To: Michael Homa; toasters(a)mathworks.com Subject: RE: Duplicate nonboot vol0 I'm curious as to how you ended up with 2 volumes called vol0. Meaning, you can't create a volume named vol0 if it already exists even if it's offline. My only guess would be that you added some drives that were part of another 2 disk volume called vol0 which ONTAP should have renamed to vol0(1) when inserted. Not sure what happened there but... So an option if you did add drives, you should know which drives you added and remove them. If you don't know which drives were added then a prior autosupport should tell you which drives were dedicated to the original vol0 and remove the ones not on the volume list. From here you should be able to rename original vol0 to another name (orig_vol) and bring online. Pop in the drives you removed and offline vol0, destroy it. Then you can rename "orig_vol" volume back to vol0.

Just thinking - you shouldn't have to boot to maintenance mode to do this, just need to make sure after the rename that the root flag is on the one you want to keep before you offline and destroy the other. But since both volumes are offline in your example you must already be in maintenance mode...

RE: GbE card for F840
by MCLACHLAN, Alan 10 May '07

10 May '07

The X1027 is a stock standard Intel Pro1000T without an Intel decal on it, sold as OEM product by Intel to NetApp and other vendors. Some vendors change firmware on the cards, but I've seen no indication that NetApp does. I have successfully used the MUCH cheaper regular boxed Intel Pro1000T in a range of test / dev filer models (F7xx and F8xx series). It should be no problem in an F840, and will show up as an X1027. Similarly the others are other Intel NIC's - been a while but I'm pretty sure the old X1025 fibre card was a regular Intel PRO1000 (1000BaseSX) card. ***NOTE: You shouldn't do this on a system with an active NetApp maintenance contract of course... :-) Regards, Alan McLachlan Technical Analyst Information Management Services Department of Education, Training and the Arts (DETA) Floor 11 Education House, 30 Mary Street, Brisbane Fax: +61 7 3237 9695 Mob: +61 429 655644 -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Tom Samplonius Sent: Friday, May 11, 2007 7:33 AM To: Dave Rubright Cc: Scott Lowe; toasters(a)mathworks.com Subject: Re: GbE card for F840 Is there any different in performance between the different GigE cards?
