Code: Select all

root@fvdwsl-base:/tmp/hitachi # umount /tmp/hitachi
umount: /rw_fs/tmp/hitachi: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))

Your current working directory is hitachi itself.

so do

Code: Select all

cd /

before unmounting

sorry you're right

can i update to 16.1 firmware?

[b1gnas]

i replaced sde but

Code: Select all

root@fvdwsl-base:/ # mdadm --re-add /dev/md0 /dev/sde8
mdadm: cannot find /dev/sde8: No such file or directory


[Jocko]

Maybe you try too quickly after plugging.
So try again

yes you can upgrade your nas (it uses the same kernel version as yours) but only when all will be restored.

[b1gnas]

it seems that there's no sde :scratch

Code: Select all

root@fvdwsl-base:/ # mdadm --re-add /dev/md0 /dev/sde8
mdadm: cannot find /dev/sde8: No such file or directory
root@fvdwsl-base:/ # fdisk /dev/sde
fdisk: can't open '/dev/sde'

So the best way is to restart the nas with all disks

[b1gnas]
