Recently one of my 2 drives has gone bad. Not that big a deal but i didn't look forward to reinstalling the whole shabang. I use LVM and both drives are used in the same volume group so i wasn't sure that it was possible to save the data and keep the machine running without having to reinstall it.
Well, i managed to keep the server running while saving the data that resides on the bad disk. Mind that only the /usr partition used PE's from the 2nd disk (the one that started failing). First i made a partition to copy all the data over from the old /usr. A lot of data was unrecoverable because of errors on that disk. I then adjusted fstab to point to the new partition to see if that would work. It did. Next i removed the bad disk from the volume group via lvreduce. I still have some PE's left to make a new /usr partition in the LVM partition. After that i copied the data over from the /usr partition to this newly created /dev/main/lv_usr (main being the volumegroup), again adjusted the fstab to reflect the change and rebooted. All services (fetchmail,exim4,spamassassin,clamav,procmail,apache ,courier,squirrelmail) kept on working just fine. To rebuild my /usr partition i started to do "apt-get --reinstall install <package>" for most packages that where installed. Most of the usr partition have now been rebuild and everything is working except my ddt-client. So i'm happy i didn't have to reinstall and it was a learning experience. I'll be closely monitoring the system to see if everything is stable but so far so good. Regards, Benedict -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
