Hi,
I had 2 luns in a zfs mirrored config.
I increased the size of both the luns by x gig and offlined/online the
individual luns in the zpool, also tried an export/import of the zpool, but i
am unable to see the increased sizewhat would i need to do to see the
increased size?...or is it not
Thanks Darren, but the snapshot taken at 4 would be the snapshot on the storage
and not on the host so the storage system wouldnt really have to bother about

2. Writes come into the app.
3. The db put in hotbackup mode.
4. Snapshot taken on storage.
5. ZFS atomic operation that commits data.
So if i do a snap restore, ZFS might revert to point1, but from the
Both levels, application and filesystem.
If i put the database in hotbackup mode,then i will have to ensure that the
filesystem is consistent as well.So, you are saying that taking a ZFS snapshot
is the only method to guarantee consistency in the filesystem since it flushes
all the buffers to th
Hi Folks,
how can i guarantee consistency for the ZFS snapshots?.
If i am running a db or any other app on my ZFS and want to take a snapshot is

Can i do something like
