8 That is the problem. I was using e2label and got a error. tune2fs
9 worked fine. I get this now:
11 root@fireball / # blkid /dev/mapper/data-data1
12 /dev/mapper/data-data1: UUID="7500437d-700c-4836-a878-29507af67a8d"
13 TYPE="ext4" LABEL="data"
14 root@fireball / #
16 Sort of hard to believe I got this far with LVM tho. I got some space now.
18 /dev/mapper/data-data1 960906608 255981512 656122832 29% /data
20 Now I can download some more of my TV shows.
22 One more question. I have two drives. A 250Gb and a 750Gb. Originally
23 the data was on the 750Gb drive. I set the 250Gb up on LVM then moved
24 things over from the 750Gb. I then added the 750Gb to the VG and
25 resized the file system. So, in theory the data is on the 250Gb drive.
26 Let's say I want to remove the 250Gb drive. I would use pvmove to do
27 that right? When I ran pvmove /dev/sdb, which is the 250Gb drive, then
28 it would remove all the data from that drive so that it could be
29 removed. Am I close?
31 I'm not planning to do that but just wanting to get a better
32 understanding of this LVM thing.
