Pool snapshot in NCS environment?

Is anyone successfully using pool snapshot in an NCS environment with
several volumes over 250GB in size and thousands of users? We would
really like to do a few snapshots a day on all volumes but I'm very
hesitant to try it in a production environment after reading some forum
posts from folks having major problems, abends, corrupted files, memory
outages etc.

Thanks,

-Chuck

Yes, but only using NW65 SP5 and Syncsort Backup Express

Re: Pool snapshot in NCS environment?


it's tricky, isn't it... the only config I know of having any success
is the exact one that tim says.

another technique that works is to do snapshots to another LUN/VDISK
and (then backing that up if you want).

Re: Pool snapshot in NCS environment?

Well, we have SP5, but (unfortunately) EMC/Legato Networker. Networker is
sort of "cluster aware" in that it backs up from/restores to virtual
servers but cannot auto recover from a failover during backup as Backup
Express can. I assume many of the prior pool snapshot issues (abends
etc.) were addressed in SP5?

any chance you can get EMC Snapview? then you take a snapshot at the SAN, and then backup from the SAN snapshot

Re: Pool snapshot in NCS environment?


yes, there were lots of NSS fixes in SP5. you also want the post-SP5
nss patch for stability.

Re: Pool snapshot in NCS environment?

We have an IBM SAN (ESS F20). I believe IBM has their own snapshot
feature. We need to look into it.

Bringing back a very old topic: are the any news on NSS shared pool
snapshots on OES for Linux? The manual for OES2015 still says they are
not supported. Still they might be quite useful for us. Is there
something on the road map? How hard could it be?

By adding to such an old post, there is an increased chance that this
escapes notice of those who know about this.

given the forum, I am assuming you are looking for Snapshotting of
cluster-enabled pools? If so, that is an option that hasn't yet made it
to Linux yet from NetWare, and the best place to is to create an Idea at
https://ideas.microfocus.com/MFI/novell-oes/
which it appears you have already done, and everyone else wanting the
feature should vote on at
https://ideas.microfocus.com/MFI/novell-oes/Idea/Detail/2004

I see it as a regular part of modern OES at
https://www.novell.com/documentation/oes2015/stor_nss_lx/data/ajhv67d.htm
l
just not during certain migrations or on clusters

Yes, exactly: Both features exist and both are essential for any
professional solution providing high-available file services. Too bad
one can not use NCS and snapshots on one pool or volume...
