Hi Cindys,
Thank you for reply.
zfs/ zpool should have ability of accessing snapshot devices with a
configurable name.
As an example if file system stack is created as
vxfs( /mnt1)
|
|
vxvm(lv1)
|
|
(device from an array / LUN say dev1),
If i take array level or hardware level snapshot, and the snapshot device for
dev1 is say dev2 then we can rename dev2 properties to access the dev2 with new
name say lv1_snap. And further access file system
with /mnt1_newmount.
This also can be done if hplvm also present.
I am looking for similar kind of ability with zfs/zpool presence.
zfs (smpool/fs1)
|
|
smpool
|
|
(device from an array / LUN say dev1)
Once I took array or hardware snapshot of dev1 and got dev2, I am looking for
something which I can access the snapshot device dev2 is accessible with
smpoolsnap or any name keeping smpool active.
And further fs1 is accessible as smpoolsnap/fs1 as read only.
If zfs/zpool do not have this support is there a way I can open an issue so
that in next releases it will be available ??
What's wrong with a snapshot of smpool, or if you want read/write, a
clone of a snapshot of smpool?
