I spent awhile searching via google, and couldn't find an answer. Probably not searching with the correct term. I have an lvm setup with two different volume groups. Both are cross disk. One group is vg, the other is media. The problem is that one of the hard disks in media seems to not work properly anymore. But for the time being i want to get this to work.
Under media i have 280G on hda devoted to volume group media, logical volume is media.
So /dev/mapper/media-media /dev/media/media. On hdb i extended the volume group media to up the total capacity to 560GB. Everything under the vg group is perfectly fine. So what i want to do is shrink media down to just hda. I'm 99% sure it hasn't written anything to hdb. The reason is I didn't expand it from the start. Before i put on fedora, i had centos on there. I copied over all my files then when volume group media was still on one disk. It took up 250GB. So i want to remove hdb from volume group media. One of the things that is making this difficult is that I cannot hook up the drive or have it running past post. When i hook up hdb it freezes on post screen. When fedora boots it states lvm failed and then displays what i'm assuming is the volume group ID for media.
Thanks any help is appreciated.
