2TB limitation

[cutty]

Hi, thanks for proxmox ve, great product.
Seen info on this but across multiple threads.

Installed V1.9 - Adaptec 5405Z with 4 x 2TB SATA drives.
Created 3.8TB RAID 10 array. Then discovered the 2TB limit.
Would prefer 1 large array but for now I deleted it and created 2 x RAID 10 arrays:
Boot array = 1.5TB. Array 2 = 2.3TB.
2.3TB array for vzdump backups which will rsync (or similar) with another location.
After Proxmox install I did this (from Udo on another thread):-
fdisk /dev/sdb
mkfs.ext3 /dev/sdb1
mkdir /mnt/vzdump_raidvol2
Edit fstab, i add: /dev/sdb1 /mnt/vzdump_raidvol2 ext3 defaults,errors=remount-ro 0 1
Reboot, check using the "mount" command - OK
In Proxmox web config|storage, I added "backups" to directory /mnt/vzdump_raidvol2.

I saw that Dietmar said this setup was dangerous. Is that for a single drive and not a RAID 10 array?
Before I move VM guests to the new host, iI would like to ask if my setup is OK or should I do it a different way?​

storing backup on the same box is probably not the best idea, finally you should make sure that you got the backups offline, e.g. on a tape. and bring these tapes to another location.

btw, the upcoming 2.0 release eliminates the 2 TB limit.

another hint: do not use /dev/sdb1 in your fstab, use UUID instead.

just run the following command to get the UUID:

blkid /dev/sdb1

Thanks Tom.

I am quite keen to get my guests onto the new server ASAP because it's much better hardware.
I wasn't sure how long until V2.0 is released and was trying to come up with something in the meantime.
Maybe I should wait for V2.0. Is it on track to be released soon?

Regards, Greg.

If you are willing to manually partition, maybe i can help you?
I made a custom 1.9 iso that does not partition (thats the manual part)
but it does install proxmox on a gpt disk and also installs grub2 so it can boot from it.

regards.

Thanks Unicron

I think I might move my important guests to the new server (as is) while I wait for V2.0.
I will concentrate on a good method for backups with off-site sync for now.
