Software RAID

[matthew]

I was thinking of installing Proxmox on a 128GB SSD then after install mounting /vz/ on a software RAID 1 partition. Has anyone done anything like that?

Hi,
do you mean /var/lib/vz ???

About softwareraid see here: http://pve.proxmox.com/wiki/Software_RAID

This is no problem.
But when you want to mount at /var/lib/vz you have to stop all services (pveproxy, pvestatd, vz, vzeventd, pvedaemon).

 

[matthew]

Won't the mount happen at reboot if its in fstab?

 

[wolfgang]

if you reboot and change the fstab sure.
I do this things online

Alright, I created /backups which is just a 4TB single drive formatted ext4 and I created /vzmain which is 4 3TB drives in software raid 10 formatted with ext4. Added settings to fstab and everything seems to hang in there on reboot. Now I should be able to disable the default 'local' under 'storage' in proxmox and replace them with these drives/directories. Will that work? Any shortcomings here? I have the main Proxmox install on a 128GB flash so my boots should be pretty quick, I hope.

You can not disable the /var/lib/vz.

you can now make 2 new local storages with your /backup and /vzmain.
or link it in /var/lib/vz

When I click on storage - local there is an enable checkbox. If I just uncheck that wont proxmox just use the new vzmain(/vzmain) storage which I have "Disk Image, ISO Image, OpenVZ Template and OpenVZ container" all enabled on?

 

[wolfgang]

No this feature work not on the default local storage.

 

[matthew]

I see what you are saying now. I cannot uncheck enabled or disable all the content options on local. Sure would be nice if I could. Is there a way to have all new containers default to vzmain rather then local for storage?

 

[matthew]

So I am assuming a better way to do this.

In fstab I commented out

#/dev/pve/data /var/lib/vz ext3 defaults 0 1

Added

/dev/md0 /var/lib/vz ext4 defaults 0 0

Rebooted and now /var/lib/vz appears to be on > 5TB software raid 10 partition. This should all work fine not?

 

[wolfgang]

Yes this would be a way.

 

[matthew]

No this feature work not on the default local storage.

Will it work with 4.0 beta 2? I created a software raid and mounted it as /vz_storage. I then added it too 'storage' and selected container. I would like all LXC containers to run there.
