Re: [linux-lvm] device-mapper: reload ioctl failed: Invalid argument



Hi,

I'm sorry to disturb you again, but I'm completly lost :-(

Do you have any idea of a command (or a tool) I can use to verify my
logical volumes ? I used pvck & vgck but everything seems ok.
At boot, I have :
couldn't find device with uuid 'dy...' (/dev/sda5)
couldn't find device with uuid 'ZE...' (/dev/sdb5)
[no error on /dev/sdc5 & /dev/sdd]
Inconsistent length: 512 1024
Inconsistent length: 512 1024
Inconsistent length: 512 1024
Inconsistent length: 512 1024
Inconsistent length: 2560 92768
Inconsistent length: 90208 90267
PV segment pe_alloc_count mismatch: 95328 != 99995
PV segment VG free-count mismatch: 95387 != 90720
Internal error: PV segments corrupted in VG_Wilco
LV LV_Racine! segment 1 has inconsistant PV area 0
etc...

If I'm not on the right ml (I'm a newbie), please, do you know another
one (or a forum) ?

Thank you.

David.
