How to tell how full the snapshot file system is?
BDF just mirrors what the parent fs is so no help there.
Any comments are appreciated.

Re: How to tell how full the snapshot file system is?
In short, check with the vendor/maker of the SAN equipment to figure this out.

Re: How to tell how full the snapshot file system is?
I do not have any HP-UX 11.11 server to check
it at the moment, but this certainly works on
HP-UX 11.31 with LVM 2.2.
For volume groups 2.2 and higher, lvdisplay
can be used to display the characteristics
and status of snapshot logical volumes.
# lvdisplay /dev/vg01/lvol1
--- Logical volumes ---
LV Name /dev/vg01/lvol1
VG Name /dev/vg01
LV Permission read/write
LV Status available/syncd
Mirror copies 0
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 40
Current LE 10
Allocated PE 10
Stripes 0
Stripe Size (Kbytes) 0
Bad block NONE
Allocation strict
IO Timeout (Seconds) default
Number of Snapshots 3
Associated snapshots /dev/vg01/lvol1_S4
/dev/vg01/lvol1_S3
/dev/vg01/lvol1_S2
Then, one could check each snapshot:
# lvdisplay /dev/vg01/lvol1_S2
--- Logical volumes ---
LV Name /dev/vg01/lvol1_S2
VG Name /dev/vg01
LV Permission read-only
LV Status available/syncd, snapshot,space efficient
Snapshot Status operative
Mirror copies 0
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 400
Current LE 200
Allocated PE 30
Stripes 0
Stripe Size (Kbytes) 0
Bad block NONE
Allocation strict
IO Timeout (Seconds) default
Pre-allocated LE 170
Current pre-allocated LE 140
Unshared LE 30
Current pre-allocated PE 140
Original LV /dev/vg01/lvol1
Timestamp Wed Apr 28 14:01:14 2010
Auto Pre-allocation Enabled
Threshold Percent 70
Otherwise, isn't your snapshot mounted?
If so, you can check it with classical
commands (bdf and others). You can always mount your shapshot if needed...
Cheers,
