[zfs-discuss] Replacing a Lun (Raid 0) (Santricity)

2008-03-14 Thread David Smith
I would like advise about how to replace a raid 0 lun. The lun is basically a raid 0 lun which is from a single disk volume group / volume from our Flexline 380 unit. So every disk in the unit is a volume group/volume/lun mapped to the host. We then let ZFS do the raid. We have a lun now

Yes! That worked to get the spare back to an available state. Thanks! So that leaves me with the trying to put together a recommended procedure to replace a failed lun/disk from our Flexline 380. Does anyone have configuration in which they are using a RAID 0 lun, which they need to

[zfs-discuss] zfs backups to tape

What's the best way to backup a zfs filesystem to tape, where the size of the filesystem is larger than what can fit on a single tape? ufsdump handles this quite nicely. Is there a similar backup program for zfs? Or a general tape management program that can take data from a stream and split it

Simple enough thanks. I assume as I start the zpool replace operation, the original LUNs will not be in rd_01 pool any more. Not that will do that, but theoretically I can perform this on a live machine without interruption, is that right? Thank you, This message posted from opensolaris.org
