Hello Guys, I found lvconvert command (in lvm lvm2-2.02.120) did not handle "--stripes" option correctly. The reproduce steps are as below, # vgcreate vgtest /dev/vdb /dev/vdc /dev/vdd /dev/vde /dev/vdf /dev/vdg # lvcreate -n lvtest -L 8G vgtest # lvconvert --mirrors 1 --stripes 3 vgtest/lvtest # lvs -o+stripes LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert #Str lvtest vgtest rwi-a-r--- 8.00g 12.21 2 But if you create LV using lvcreate command directly, the command succeeds with stripes. e.g. # lvcreate --mirrors 1 --stripes 3 -L 4G vgtest # lvs -o+stripes LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert #Str lvol0 vgtest rwi-a-r--- 4.01g 8.67 6 I also use lvm2-2.02.180 to reproduce this issue, the lvconvert command works like before, but the command will print out a message, like that, # lvconvert --mirrors 1 --stripes 3 vgtest/lvtest Command does not accept option: --stripes 3. Why do we can not use lvconvert to do like that, design issue? but lvcreate can do that. What limitations are there between mirrors and stripes?
