Ciao a tutti.
In una macchina con Debian Squeeze aggiornata mi accingevo a distruggere
uno snapshot per ricrearne uno nuovo, ma mi ha dato una serie di errori,
prima mai verificati. La bancata di dischi non evidenzia led di errore
fisico. Gli errori sono questi.
root@xen37:~# lvdisplay | grep indicia
/dev/dm-9: read failed after 0 of 4096 at 0: Input/output error
LV Name /dev/LOCAL_DISK/indicia-disk
/dev/LOCAL_DISK/indicia-snap-002 [active]
/dev/LOCAL_DISK/indicia-snap-003 [active]
LV Name /dev/LOCAL_DISK/indicia-swap
LV Name /dev/LOCAL_DISK/indicia-snap-002
LV snapshot status active destination for /dev/LOCAL_DISK/indicia-disk

Do you really want to remove active logical volume indicia-snap-002?
[y/n]: n
Logical volume indicia-snap-002 not removed

Nel frattempo cerco un po' su Google e predispongo se ci riesco nuovi
salvataggi di sicurezza
Avete idee sul da farsi, prima di tentare un boot ?
Grazie
