Ho un setup LVM su Debian 7.8 con kernel 3.2.65-1 + deb7u1 con OpenMediaVault
LV è composto da 4 dischi
Disk /dev/sdb: 4000.8 GB, 4000787030016 bytes
Disk /dev/sdc: 2000.4 GB, 2000398934016 bytes
Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes
Disk /dev/sde: 1500.3 GB, 1500301910016 bytes
A partire da ieri sera, l'accesso alle azioni situate sul LV ha iniziato a rallentare, quando finalmente le azioni sono diventate totalmente non rispondenti.
Syslog mostra ripetutamente il seguente messaggio
ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0

Ho rintracciato che /dev/sde
è il disco problematico e non riesco più a far funzionare LVM perché si blocca.
Dovrei avere abbastanza spazio libero su sdb
, sdc
e sdd
per rimuovere sde
ma qualsiasi comando come pvmove
appendere semplicemente quando si tenta di leggere sde
.
Qualche suggerimento o il mio volume è brindisi?
Grazie!
