OK. I learned something. Check this out:
root@fireball / # df
Filesystem 1K-blocks Used Available Use% Mounted on
<< SNIP >>
/dev/mapper/sdb--vg-test
51606140 48910048 74652 100% /mnt/temp
root@fireball / #
This is what I am doing here. As I posted a while ago, I created a 50Gb
LV. I attempted to copy about 75Gbs to it which filled it up but I
wanted to make sure it would. lol Then I used lvextend -L100G
/dev/mapper/sdb--vg-test to make it larger. I read I could do the same
thing with lvresize but the example I was reading showed lvextend. This
is what I got now:
root@fireball / # lvdisplay
--- Logical volume ---
LV Name /dev/sdb-vg/test
VG Name sdb-vg
LV UUID mixhOb-La6D-BwG4-Uz3l-P0ci-oGg5-YI3mN8
LV Write Access read/write
LV Status available
# open 1
LV Size 100.00 GiB
Current LE 25600
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 254:0
root@fireball / #
So, according to that it is 100Gbs which is what I wanted. Thing was,
it didn't work. So, hmmmm. Light bulb moment. Resize the file system
silly. After that, success. So, I created something that wasn''t big
enough, filled it up, made it bigger, fixed the file system and now it
is working. All while online too. That is the weird part.
Still not comfy putting a OS on it but it is cool so far.
