10.4.4 Disk Space Reporting Errors

[OCSHOSTING]

I thaught id pop on here before i call up my vendors..

We are currently about to start moving 30 control pannel servers over to plesk, but we have hit a snag, after purchasing 16 of the finest Quad Core AMD Servers, plesk has thrown a wobbler.

Server: Cent OS6 - Plesk Pannel 10.4.4
AMD Quad Core 2.5Ghz
8GB DDR
2 x 750GB SATA Software RAID 1

But as you can see from the attachment plesk has other ideas, and we just discovered CentOS knows whats inside....

Any Suggestions???? Same happens when we reimage to CentOS5 with Panel 10.4.4 X86_64 as it does on CentOS 6

Pleaseeee tell me i dont need to have all 16 servers pulled and looked at PLEASEEEEEE

Cheers

Im asuming your server is provided by 1and1, based on the structure of the partitions.

Starting from that sumption.

do df -h

that should give you the volumes, size, and where it is mapped.

after doing that do

lvs

this command will show you how much space is assigned to each LV volume.

then do

pvs

to see how much free space you have available to assign to your LV!

next you need to do is assign that free space to your LV

we do this by using the lvextend tool, lvextend stands for "Logical Volume Extend"

as a recommendation, i would tell you to have /usr with at least 10 GB

so do

lvextend -L +6GB /dev/mapper/vg00-usr

this will "ADD" 6 GB to the LV(Logical Volume) /usr

then do again pvs

to check how much free space it has now.

and add the remaining space to /var

lvextend -L +RESTGB /dev/mapper/vg00-var

then now do lvs to confirm the changes.

lvs

when thats done, we have to force the growth of the LVs, to do that, we use xfs_growfs (if you use xfs partitions) or resize2fs (if you use ext4 partitions)

if you use xfs:

xfs_growfs /var
wait until its done, then
xfs_growfs /usr

if you use ext4:

resize2fs /dev/mapper/vg00-var
wait until its done(it takes a while if you are adding lots of space), then
resize2fs /dev/mapper/vg00-usr

then you can check your changes with

df -h

you should now have your hard drive space (in logical volumes) assigned correctly.

restart plesk, or even the servers, and plesk should report the correct ammount of space assigned to each unit.
