Hi,
Our system RHEL4:
# uname -r
2.6.9-22.EL
# rpm -qa | grep lvm
system-config-lvm-1.0.16-1.0
lvm2-2.02.01-1.3.RHEL4
We would like to make up to 8 snapshots/day of the same original LV.
To be able to keep all the snapshots for an entire day, we thougt that we could
deactivate a snapshot before creating a new active one.
----current VG/LV config----
# lvdisplay
--- Logical volume ---
LV Name /dev/vg1/lv1
VG Name vg1
LV UUID SjIv1d-XedO-o9mZ-7EKa-zNcj-bX6m-BhfAZQ
LV Write Access read/write
LV snapshot status source of
/dev/vg1/snap1 [active]
LV Status available
# open 1
LV Size 3.16 GB
Current LE 810
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:0
--- Logical volume ---
LV Name /dev/vg1/snap1
VG Name vg1
LV UUID U7DjZJ-HTDZ-5L0P-QxWD-moxK-KqRG-o03wQf
LV Write Access read/write
LV snapshot status active destination for /dev/vg1/lv1
LV Status available
# open 0
LV Size 3.16 GB
Current LE 810
COW-table size 424.00 MB
COW-table LE 106
Allocated to snapshot 47.46%
Snapshot chunk size 8.00 KB
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:3
--------------------------------
Using lvchange to deactivate the current snapshot reports errors:-(
# lvchange -v -an /dev/vg1/snap1
Using logical volume(s) on command line
Can't change snapshot logical volume "snap1"
Are we missing something?
