Aqui está um dos meus servidores Solaris 10 depois de algumas substituições de disco em um zpool
pool: volume
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
scan: resilver in progress since Wed Jul 6 11:43:51 2016
207M scanned out of 36.7T at 1.48M/s, (scan is slow, no estimated time)
207M scanned out of 36.7T at 1.48M/s, 7235h37m to go

errors: No known data errors
O status da verificação retorna para 0.00% done a cada 10-15 minutos, reiniciando assim a recuperação. Aqui está a saída de echo "::zfs_dbgmsg" | mdb -k .
iostat -En mostra um número alto (e crescente) de erros em todos os discos.
zpool iostat -v volume mostra atividade normal de redimensionamento (gravar em discos novos, lidos em discos antigos)
/var/adm/messages está cheio de mensagens como esta:

Há algo que eu possa fazer para que o resilvering seja concluído para que o pool retorne ao estado normal?
