Re: [linux-lvm] Follow-up 2: Help: lvm 0.9.1_beta3 oops (can't get my data)



Looks like it didn't work.


[root btexi0c1 perfect]# vgcfgrestore -n w0 /dev/hda8
vgcfgrestore -- VGDA for "w0" successfully restored to physical volume "/dev/hda8"

[root btexi0c1 perfect]# vgcfgrestore -n w0 /dev/hdb3
vgcfgrestore -- VGDA for "w0" successfully restored to physical volume "/dev/hdb3"

[root btexi0c1 perfect]# vgchange -a y
