iSCSI & SAN

[loisl]

Hi,
yesterday I came across Proxmox and very enthusiastic ... almost exactly what I was looking for a long time.

I only wish now possible to have all the data on the SAN.
glusterfs is still somewhat experimental and I have the v1.6 in "Storge List" already found "Add iSCSI target.
Now my question: Can this satisfy my desire and all the virtual machines work on the SAN or is it only for backup?

Thank you for your help
Best regards
loisl

yes, you can store all VM´s on SAN, for KVM guest its integrated in our gui, see http://pve.proxmox.com/wiki/Storage_Model.

OpenVZ: uses only local storage (but if you know what you are doing you can think of mounting a iSCSI lun on /var/lib/vz instead of local disks)

For backup, we recommend to use a NFS share (and archive these backups regularly to a tape).

Hi Tom,

thanks, the test works quite well.
I have the same iSCSI mounted as /var/lib/vz.
Works perfectly.

Only one problem:
on boot I get an "fsck died with exit status 8
failed (code8) "..." fsck.ext3: No such file or directory while trying to open / dev/sdb1 "
Continue with Ctrl + D later it will be integrated correctly anyway!

Since that time the network is not active yet!
someone has an idea?

best regards,
loisl

You need to change pass-num flag for this disk to 0

P.S. taken from wikipedia:

pass-num Controls the order in which fsck checks the device/partition for errors at boot time. The root device should be 1. Other partitions should be either 2 (to check after root) or 0 (to disable checking for that partition altogether).
