Hello everybody,
I have the following configuration: a thecus n2100 with two disks
configured as raid1 (actually there are three partitions on each disk: a
non-mirrored swap partition and two data partitions, one small and the
other large. These latter partitions are part of two raid1 mirrors
across the two drives and above them I built lvm2 volumes).
Anyway last night one of the disks failed. I thought it was no big
problem: monday I'll buy a new disk and replace the failed one.
But then I tried to shutdown (via shutdown -r now) and I cannot.
I get the usual "The system is going down for reboot NOW!" message, in
/var/log/messages I see
May 17 09:06:56 thebian shutdown[5507]: shutting down for system reboot
(thebian is the name of the n2100, sorry for the pun...)
but then, nothing happens. After *many* minutes some of SCSI errors
appears in /var/log/messages
May 17 09:23:34 thebian kernel: sd 0:0:0:0: SCSI error: return code =
0x00040000
May 17 09:23:34 thebian kernel: end_request: I/O error, dev sda, sector 0
May 17 09:23:34 thebian kernel: sd 0:0:0:0: SCSI error: return code =
0x00040000
May 17 09:23:34 thebian kernel: end_request: I/O error, dev sda, sector 0
and so on, but I think they are completely unrelated to the shutdown as
with a dead disk they appear even during "normal" operation. Apart from
this, nothing. runlevel prints
2 6
so I'm stuck in the middle of the shutdown, but why? I suppose a console
would help in this case but alas my n2100 has no serial connector :)
Now, before going the pull-the-power-cord way ;) I'm wondering if
somebody has seen this or has advice.
Also: is pulling the power cord safe in this scase? I mean: will the
raid rebuild? I think it will but has somebody advice?
PS: anyway, I backed up everything :)
