Hello,
so I have asked on another thread which is getting quite long, and got no reply. I need to make this work ASAP since my main production server is down due to maxed out storage inside a specific CentOS VM,..
Basically, I have added 3X 2TB drives in a RAID5 config to my node, and I would like to dedicate 300GB of it for VM backups, and the rest (roughly 3.34TB) for general file storage (NOT backups, ISO, images, etc)
I have created a PV on the entire array (3.64TB) called datastore
Then a single VG occupying the entire PV
Then finally two LV, first one of 300GB called backups (/dev/mapper/datastore-backup) and another 3.34TB called storage (/dev/mapper/datastore-storage).
I have modified fstab to automount backup to /mnt/backups and under WebGUI I have added /mnt/backups as backup storage.
Is this optimal??
I have not found a way to assign the storage LV of 3.34TB to my CentOS VM.... How do I do that?!?!
I tried to mount it in proxmox via fstab, then create a raw VHD of 3.3TB but proxmox complained 3.3TB was TOO big for a VHD image.. I have not found a way to use that space yet and need it sooner than later because mysql (in CentOS) dies repeatedly due to lack of space...
Anyways, the general idea is to use that 3.64TB RAID5 in a flexible manner (in case I add more drives to the backplane) and dedicate 300GB to backup & the rest to storage needs..
If anyone could shed some light on this for me I would appreciate greatly..
Thanks! ;)
