Filer must be able to resolve user name to user UID. How exactly it does it (local /etc/passwd, LDAP, NIS or whatever) is irrelevant. But if you want to make sure that the same UID resolves to the same user name, the best is to make central user database and let both filer and server to use it. ... View more

a) Fractional_reserve plays role exactly when you create snapshot – not “at some point in the past”. So every time you create snapshot it reserves exactly the amount of space that LUN currently occupies on NetApp. b) When host deletes data in filesystem, space is not freed from the NetApp point of view. So if it was huge once, it remains huge now. Unfortunately, the only way to reduce space consumption is to create another LUN and copy data over and destroy existing one. When doing this new LUN could temporary be set to no space reservation to reduce consumption. ... View more

It is not the question of “ahead” or “behind”. Consistency point happens as a single transaction – which means, it will wait for the slowest drives to complete. Even if SAS has completed, CP will not be complete until SATA catches up. OTOH unless this causes back-to-back CP, I do not see how it matters. Whether CP completes in 0.5 second or 9.5 second, it does not really matter if it completes fast enough before second half on NVRAM fills up. ... View more

When you say “cluster failover” do you mean NetApp takeover/giveback or host clustering? For NetApp the usual reason is improper configuration of timeouts in host’s drivers. Another possibility is incorrect connection (e.g. no path via partner). ... View more

If LUN in snapmirror destination has to be available read-write, you need to either break mirror or use flexclone to create writable LUN. That's correct. I do not have practical experience with OSSV so I do not know whether it tries to access LUNs read-write and can it be changed. Volume FlexClone is based on specific snapshot. This is snapshot is not updated anymore. So if you want to access newer LUN version, you need to unmount LUN, destroy flexclone, create new flexclone based on more recent snapshot and mount LUN again. Have you looked at SnapProect? It sounds like it does exactly what you need - offering file based restore (with history, file browsing etc) together with disaster recovery (SnapMirror). ... View more

If you have both CIFS and NFS you should be able to access root volume and delete files. You say this operation fails, which normally is due to restricted CIFS that comes with FCP/iSCSI licenses.

DR involves really far more than just storage failover. So it would be misleading for a storage vendor to claim it offers complete DR setup procedure.

No, these two options are not the same. Internally NetApp maintains several versions of each file name. Setting ucode=on forces it to always create UNICODE file name in addition to “native” name supplied by client. Setting language to whatever.UTF-8 basically says that client is using UTF-8 as native character set. Are you using CIFS or NFS on this volume? ... View more

You always can access previous snapshots and manually copy data from them. How exactly depends on which protocol you use to access filer. E.g. if you are using CIFS, you can use standard Windows feature Previous Versions to access snapshots. ... View more
