I'm running LVM 2 on Fedora Core 3 on an Intel P4 w 1GB ram.
I have 2 A16U-G2421 (http://www.infortrend.com/main/2_product/a16u-g2421-1.asp) hooked up to it.
2 LVM's made, both seems to be working, but very slowly.
Today I noticed that the server was VERY slow. After checking around I find that the exported disks on one of the
raid boxes has weird partition info.
I have exported 3 disks from this box.
I'm going insane trying to resolve this without loosing this weekends jobs.
I'm a bit leery about just changing things in the partition befor I can get a dump of the file system thou :)
anyone got any tips?
