Ubuntu + Raid ERROR
 
Hello everyone, good night.
Today I had a serious problem on my server. The operating system is ubuntu 10.10. The machine is HP DL120. I have 4 hard drives each with 1.5TB RAID1 +0 (software raid because this controller was not found in installation of ubuntu). I do not know why, but the machine crashed today 6:00 PM and returned after 30 minutes alone, without rebooting. The syslog messages are:

I do not understand the errors, but I suspect it is something related to the raid. What are these errors? Please, what should I do to eliminate this error?

Thanks.

Hello again.

I am reading about fake raid. Likely my fault: Do not have a swap partition created.

I can create a swap partition on a system already installed on fake raid?

Thanks.

guimnk 13th May 2011 05:27

I'm running the following commands:

Code:

root@turbo:/# dd  if=/dev/zero  of=/swapRaid  bs=1024 count=4194304
root@turbo:/# chmod 600 /swapRaid

root@turbo:/# mkswap swapRaid
mkswap: swapRaid: warning: don't erase bootbits sectors no disco inteiro. Use -f to force.
Setting up swapspace version 1, size = 4194300 KiB
no label, UUID=1b3ad17b-23d0-4a3b-bb61-a05c1429d4bc
root@turbo:/#

I will have problems if you continue with:

Code:

swapon swapRaid
on fake raid???

Thanks

guimnk 13th May 2011 05:35

No errors :)

Code:

root@turbo:/# swapon swapRaid
root@turbo:/# free -m
            total      used      free    shared    buffers    cached
Mem:          3954      3082        872          0        48        283
-/+ buffers/cache:      2750      1204
Swap:        4095          0      4095

Now, I'll follow up and see the performance of the server. I want to end
slowness and errors such as today. I hope to help someone with this post.
