I'm currently using cLVM. I moved a RAID0 disc to a RAID5 disc using
pvmove on my first node and removed from it's volume group using vgreduce.
After that I deleted de first disk. Now on the secondary node I'm getting
IO errors like that:
[root at inf18 ~]# pvscan
/dev/sdb: read failed after 0 of 4096 at 214748299264: Input/output error
/dev/sdb1: read failed after 0 of 512 at 214745481216: Input/output error

Total: 5 [327.66 GB] / in use: 4 [235.98 GB] / in no VG: 1 [91.69 GB]
[root at inf18 ~]# vgreduce padicat.bench /dev/sdb1
Physical Volume "/dev/sdb1" not found in Volume Group "padicat.bench"
Also I can't use the LV on the VG that was that disk. Anyone can help me
on telling LVM not to use sdb anymore? It's a production system, so by now
reboot it it's no an option to me.
