Kernel Panics


Recommended Posts

I recently picked up one of those super micro 4u servers from Tams and swapped everything over but couldn't get the network to work. I finally got that fixed but then I started having kernel panics. Currently I"m stuck at "Kernel panic - not syncing" <4>REISERFS panic (device md2): journal-003 check journal_end: j_start (2835) is too high

 

This is after I was having problems with md1 so I ran a reiserfsck that told me to rebuild tree so I did. When the system was coming up disk 3 was showing as a red ball although fdisk -l confirmed all my disks were there. I took the array offline to go into maintenance mode and then it showed Parity drive was not there even though when the array was up it had a green ball. After running reiserfsck rebuild tree on md1 it appears that parity is ok in unraid now but when I reran the check on it all sorts of stuff was coming up although I didn't get a chance to finish the check because I need to shut down for this morning for a bit and it was taking too long.

 

Anyway, When I went to take it out of maintenance mode so I could capture syslog because /boot wasn't writeable that is when I had the above kernel panic on md2. So I'm not really sure where to go. Should I just put all these drives back in the old case since everything was working fine then and then try to get back to a working system... or what? I don't really know where to go from here.

Attached is the telnet output for the reiserfsck on md1 from last night

I should also note I'm on 5.0-rc12a. Also when I tried to shut down my array so I could put it into maintenance mode last night it hung but I think since md1 was read only already because of errors it let me go ahead with the reiserfsck. This morning I didn't have any problems getting into maintenance mode after I rebooted.

I came home to find out that disk 1 is showing unformatted now while disk 3 is still red balled. Which I'm sure is because I ran reiserfsck --rebuild-tree and also probably because when I did that I wasn't in maintenance mode. Had I been in maintenance mode parity would have picked up the changes. So I'm an idiot.

 

Then I realized my flash drive was corrupt which is why I couldn't write the syslog to it. I've taken care of that thanks to a tip from the amazing Joe L in another thread to run chkdsk on it from windows. That looks good so here is my most recent syslog attached.

 

I still don't know where to go from here. I think I will first try to run some smart commands on my disks to make sure they're good. If they are I'll probably start the reiserfsck on md1 again.

Now my entire daggone flash drive was corrupt and chkdsk repair moved every file to lost and found except the 2 smart reports I grabbed before shutting down last time. Holy cow. Now I have no idea what is going to happen. Based on this here thread I should be able to just reinstall onto my flash drive, drop my key in, and go. http://lime-technology.com/forum/index.php?topic=20505.15

 

So now I'm resyncing parity. Again, attached are the 2 smart reports. SDB was red balled and SDC is currently showing unformatted. On a positive note sdb no longer has a red ball next to it and I'm pretty sure I don't see any issues with it in the smartlog.
