Hi all,
I have a problem to day with an LVM on a machine I have been asked
to "sort out"
I am not too familiar with LVM so wondered if someone could look at my
output and put me straight.
This is what I think I can see:
The VolGroup00 contains 2 physical disks, on is 29.90GB and one at
75.00GB these are on a san. This gives me a LOGVol00 of 102.91GB and a
LogVol01 of 1.94GB according to lvdisplay.
Total LE are 3355 and they are 32M in size this = 104.8GB
It shows I have no extents free so ???
Why can I only see 28G of disk space?
How do I check and create more
space for the root filesystem?
The only thing I can think of is I have exceeded the number of extents allowed?
if so why did it show 3355 in use?
Cheers
Code:
