This is MIME -----SKER1080632731-- Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Dear Sirs. I ran into big trouble after a thermal RAID failure. Our main server is a dual PIII with a Tyan Thunder 2500 main PCB, a AMI MegaRAID Enterprise 1600 four channel RAID controller attached to 9 IBM DDYS 35GB harddrives. 8 disks build up a RAID level 5, one disk is hotspare. Aber several problems in the past with cooling disks in the RAID failed due to termal issues. Two days ago I got a similar problem. One disk died spontanously and the RAID got rebuild on the hot spare disk. But after completion, it seems that another disk failed again. I took the suspected disk out of its cabinet and put it back into its slot (sometimes after such a failure RAID looses disks maybe due to electrical problems, I did not inevstigate further more). After a reboot the server got up again - but lost a partition (or so called slice)! I think the reboot has been performed while the RAID controler was rebuilding the array, but I don't know. It is really corious to me that only the first slice of the amrd0s1 array, containing / /usr /var /tmp and a swap partition, is still active, while the second slice, amrd0s2 seems to be lost. No fsck is performed on this slice (conatining /usr/homes /usr/local), system reports an error "no such device" or similar. Hell, what happend? Where has the second slice been gone? If there is a way to reinitiate a recovery or RAID rebuild or rescue/recover the lost partition, please report me under this eMail address, I would appreciate any comment, help or tip. Many thanks for your help in advanece, O. Hartmann ohartman@web.de _______________________________________________________________________ ... and the winner is...
