CommVault Archiver module (HSM) and OnTap 7.3?
by John Stoffel 02 Oct '09

02 Oct '09

Hi all, Does anyone know what the bug number that is fixed in OnTap 7.3.x so that CommVault 7.x will work properly with stubs to restore files which have been moved off to secondary storage? We're currently running 7.2.6.1 and 7.2.6.1P8 on our filers, and I just want to see if I can figure out which fpolicy (my assumption) bug was fixed. As I understand it, the bug was that on the first access, the file wasn't restored, but on the second it was. This could lead to problems if users found the stubs and either edited them or worse, thought their data was hosed. Of course, moving to 7.3.1.1 won't be too hard, but with all the new iSCSI Luns we've been adding, it makes upgrades harder than when we were just NFS/CIFS exports. Reboots are much simpler then. *grin* THanks, John John Stoffel - Senior Staff Systems Administrator - System LSI Group Toshiba America Electronic Components, Inc. - http://www.toshiba.com/taec john.stoffel(a)taec.toshiba.com - 508-486-1087

Re: missing ops? messages file and `qtree stats` data inconsistency

I compared the output of the three following stats, 60 seconds apart, and clearly the qtree stats is the smallest of the three: qtree stats 972297 cifs stat 2396439 uptime 2395260 However, given our workload, we have tons of CIFS getattrs, and a small fraction of reads or writes. So, I think our suspicions are true (not all ops are reported by qtree stats) but the specific excluded ops in our case seem to still be off. Hrmph. Until next time...

Re: Other OPS?
by Mike 02 Oct '09

02 Oct '09

Metadata work, mostly - directory crawls, access checks, things like that (in CIFS). In NFS, ACCESS, READDIR, READDIR+ , stuff like that. I think you can use 'cifs top -s ops' to see the busiest clients hitting the system. If the ones at the top have very high ops, but not many reads/writes, those could be your guys. That said, it's all about latency. If it isn't driving latency higher, shouldn't be a concern. Those are different stats commands, though, can't remember right now...... --- On Fri, 6/5/09, Page, Jeremy <jeremy.page(a)gilbarco.com> wrote: > From: Page, Jeremy <jeremy.page(a)gilbarco.com> > Subject: Other OPS? > To: toasters(a)mathworks.com > Date: Friday, June 5, 2009, 3:10 PM > > > > > > > > > > > > > > > > What > causes other ops? > I understand that pretty much everything that hits the > filer requires something > but I am seeing what looks like a very high number of other > ops when I do a > stats show.

Snapmanager - eMail issue
by Buerger, Andreas 02 Oct '09

02 Oct '09

Hey Toasters, We're experiencing problems in our Snapmanager environment: Since our eMail team changed the mailrelay hosts, we are not able to send emails with Snapmanager applications anymore. We tracked the problem down to the root cause and found that Snapmanger doesn't use the FQDN in the SMTP Helo cmd to connect to the email relay. According to RFC 821 (SMTP Protocol) the FQDN has to be submitted otherwise the mail relay "normally" does not accept the message (some mail relays do, some don't and ours doesn't accept it). Did anybody run into the same issue before? Is there any known solution or workaround for this problem, without installing any additional apps on windows ?

R: High CPU utilizations and file I/O

Good question!

Are the VMDK's aligned? If Yes, continue with volume stats. If No, stop everything, there's your problem, no way around it.

The customer states that in the NFS volume for VMware there's an high activity of continous destruction and building of VMware vdisk... Is there some tool that can let me understand which volume is under stress and in case move it on the other head? Or maybe this filer is undersized for the job that has been asked... Regards, Dott.
