[Tech] disco raid che dice di essere impegnato

[Leonardo Boselli]

root@mmm:~# raidhotremove /dev/md0 /dev/hdg2
/dev/md0: can not hot-remove disk: disk busy!

    strano ... se è "hot" ???
    per sicurezza allora:
root@mmm:~# umount /dev/md0
root@mmm:~# raidhotremove /dev/md0 /dev/hdg2
/dev/md0: can not hot-remove disk: disk busy!

    insistiamo:
root@mmm:~# /etc/init.d/raid2 stop
Stopping RAID devices: /dev/md0 done.
root@mmm:~# raidhotremove /dev/md0 /dev/hdg2
/dev/md0: can not hot-remove disk: array not running!

    lo dicevo io ....

root@mmm:~# /etc/init.d/raid2 start
Starting RAID devices: /dev/md0 done.
root@mmm:~# raidhotremove /dev/md0 /dev/hdg2
/dev/md0: can not hot-remove disk: disk busy!


MA CHI LO IMPEGNA ? (anche sull'altro volume del raid da la stessa
 cosa) ? come lo smonto ?

aggiungo:
root@mmm:~# lsraid -A -p
