Hello, sorry for delay. I might found why lv_var was displayed exactly 5 times for vg00/lv_var and reason is LV was extended several times and its Segments are spread to 5 physical locations on PV. I've tried to --uncache vg00/lv_root and output is same also for vg00/lv_root and LV is shown 4 times as LV is split in 4 Segments. So I performed 'sudo pvmove --alloc anywhere -n /dev/vg00/lv_root /dev/sda /dev/sda' to tighty LV to one Segment, and after another --cache & --uncache operation is all OK. Same applies also for vg00/lv_var which looks normal now and it's displayed only once. If I split LV to more segments again LV is display multiple times.
If you feel that this is OK , feel free to close this bug.
Hi Ladislav, This issue can be replicated easily as below: tw1:~ # vgcreate vgtest /dev/vdb1 Volume group "vgtest" successfully created tw1:~ # lvcreate -L 3G -n lv1 vgtest Logical volume "lv1" created. tw1:~ # lvcreate -L 3G -n lv2 vgtest Logical volume "lv2" created. tw1:~ # lvextend -L +1G vgtest/lv1 Size of logical volume vgtest/lv1 changed from 3.00 GiB (768 extents) to 4.00 GiB (1024 extents). Logical volume vgtest/lv1 successfully resized. tw1:~ # lvs -o+cache_mode LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert CacheMode lv1 vgtest -wi-a----- 4.00g lv1 vgtest -wi-a----- 4.00g lv2 vgtest -wi-a----- 3.00g ***while*** tw1:~ # lvs -o+cache_total_blocks LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert CacheTotalBlocks lv1 vgtest -wi-a----- 4.00g lv2 vgtest -wi-a----- 3.00g This is by design, because "cache_mode" is under "Logical Volume Segment Fields", every fields in this category will be displayed per "segment" as you've pointed out. See: tw1:~ # lvs -o help Logical Volume Device Status Fields ----------------------------------- ... cache_total_blocks - Total cache blocks. ... Logical Volume Segment Fields ----------------------------- ... cache_mode - For cache, how writes are cached. ... So close as INVALID.
