[Qnap TS-210] don't boot anymore
Hi all,
I got a Qnap TS-210 last week. I installed Debian Sid on it
(with 2x2 TB hdd, RAID-1, ext4) and all was good (rebooted it 3
or 4 times, copied GBs of data on it, etc.) until Monday evening
when I asked it to reboot and it got stuck (red/green flashing
status light, no disk activity). I tried quite a lot of things
but I don't have a serial cable.
The short version:
It can boot in recovery mode (TFTP) with the Debian Installer
Testing image. So I can have an ssh console/rescue tool.
It can't boot on any installed Debian (old one, new one,
Testing or Sid, ext3 or ext4 (hmm, I realize I always kept the
RAID-1 though)).
The longer one:
First, I got the disks out and checked them: they are ok.
(Well, I realized (too long) after I could use the installer as
a console/rescue tool. I would have spent less time moving my
disks around. Well, I do stupid things like that sometimes.)
The logs: nothing, it stops logging in /var/log/dmesg after a
few lines. Other files are empty (or with no more lines than
before the reboot).
I introduced echo lines in some boot scripts (actually, mostly
in /etc/default/*) to easily track where it stopped. I thus
realized that:
1. It can't write content to files. It can just create them.
(That's weird to me.)
2. It begins executing rcS.d scripts: it loads
/etc/default/{console-setup, devpts, ifupdown, keyboard,
locale, rcS, tmpfs}. As it doesn't load bootlogd nor
mdadm, I conclude that it stops very early and maybe waits
for some input.
At that stage, I tried reinstalling anew. The installation(s)
went well, but the installed system didn't boot either. (First
with ext4 again, then with only the / partition, in ext3, as I
thought maybe because it can create files but not populate them
then it may be related to the file system. Testing or Sid (but
they have the same kernels so no real difference).)
Then, I restored my not-working-anymore-installation (the disk
part, I did a tarball the first time I got the disks out) and
tried making a TFTP boot image for it with an older linux-image
(2.6.32-5-21 instead of -23). I constructed the initrd from the
2.6.32-5-23 one, replacing only the modules. It boots as the
others: few seconds disk activity then silence and still
flashing status, no net.
Then, I installed linux-{image,base}-2.6.35-trunk on my
installed system from a chroot from the ssh console of the
installer (I had to force some little things in order to avoid
error or warning messages). Same results.
What I haven't tried:
Reinstalling the Qnap boot image (not really happy with that).
Not using RAID-1.
Any idea of anything else I can try?
By the way, I'm also looking for a TTL-serial converter (with
the good connectors or adapters) in France or Europe (French or
English, and Euros would be better), if you happen to know a
trustworthy (and not too expensive) retailer...
