Re: Linux in an LPAR - recovery?
As others have found out to their dismay, no, it doesn't. Sounds like a good subject for an RFE to me.

We had an experience some months ago that seems seems eerily similar to yours, but under somewhat different circumstances... We had a z800 at the time, running a z/OS sysplex on several LPARs, along with a VM LPAR with Debian running as a VM guest. Debian boots off a VM Mimidisk, but we also had filesystem mounted on a dedicated drive. For some reason I can't remember, we made some changes to the z800 that required a power-on-reset. When the system came back up, we couldn't boot Debian. We wound up having to reinstall Debian onto that boot drive, but the filesystem on the dedicated drive was intact. (Fortunately, that file system had most of our critical data!)

What is the actual message you are getting. With sles9 if you have added dasd after the initial install and you didn't run mkinitrd and zipl after adding the dasd you will a similar error but the system will come up. In this case go into your /etc/fstab and comment out the devices that you can't find, reboot and if you come up OK, go back and define the missing devices, run mkinitrd and zipl, reboot and hope. john -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: Linux in an LPAR - recovery?
As Jeremy stated, we would need some more information. If the system is asking you to enter maintenance mode and run fsck (whether for ext2/ext3 or reiserfs), go ahead and try that first. If the file system(s) that is/are damaged is _not_ your root file system, you could try removing them from /etc/fstab (make a backup first) and then rebooting. Once you're up, you could run the fsck, then mount them to see if you lost anything. (Although if you did, you'll get that clue during the fsck itself. Lots of ugly messages, etc.) Also, what file system were you using? If the system really was dormant, and you were using a journaled file system, I would not have expected this problem to happen. It should have be able to replay the journal and come right back up.

Re: Linux in an LPAR - recovery?
Here it comes.. Wait for it... "It depends..." What exactly are the messages you are getting? Sometimes it's a simple as letting it come up borked and then running the appropriate filesystem repair tool (e2fsck, etc) with the right switches, rebooting again, and all is well.
