Hi,
This is my current config:
/dev/md0 -> 200 MB -> sda1 + sdd1 -> /boot
/dev/md1 -> 36 GB -> sda2 + sdd2 -> form VolGroup00 with md2
/dev/md2 -> 18 GB -> sdb1 + sde1 -> form VolGroup00 with md1
sda,sdd -> 36 GB 10k SCSI HDDs
sdb,sde -> 18 GB 10k SCSI HDDs
I have added 2 36 GB 10K SCSI drives in it, they are detected as sdc and
sdf.
What should I do if I want to optimize disk space?
The simplest solution would be to create /dev/md3 out of sdc1 and sdf1,
and add it to the VG, and increase the size of my /vz logical volume.
However, if I could convert that to a RAID5 (it could be possible to
re-install, but I would rather not), I could have 6 drives in RAID5, so
I'd have 5x36 GB (180) of space available total, instead of 3*36 (108).
180, you mean 2 X 5x18
Oh, I just realized I have 2X18 and 4X36. I have 2 other 36 GB HDD
here. Maybe I could have a 6x36 RAID5 this way. Does it matter if I
drop the 2x18, to drop the 2x18 complexity,
or keep them in mirroring, and maybe on another VG,
to backup/store more critical data
Ok, but the server can only have 6 HDD.
So, first step, how would I replace the current 2X18 by the 2x36 that I
put in the server yesterday?
(BTW thanks a lot for your help, it is very interesting)
Regards,
Ugo
