*SOLVED* vps's directory on different hard disk [message #14313]

Hi!

Is it possible, to have a VPS's directory on a different device, than /vz? For example I have two 140G hard drives, in raid1, and on top of that I have LVM, for the ability to have snapshots, and this is mounted az /vz. I'd like to have /vz/private/101/var to be on another device. Can I do that?

Thanks in advance!

You can create a bind mount to /vz/root/101/var after VE start. This procedure can be automized by <veid>.mount file.

But then the size of the VPS can't be bigger than the size of the hard drive, containing /vz. I know about raid10, or multiple phisical devices with LVM, but I'd like to avoid theese.

Thanks anyway.

Sorry, don't get you.

Assume, you have /vz on /dev/hda1. It means, that VEs private files are located in /vz/private/<veid>. Then you have one more hard disk: hdb. After `vzctl mount` command you can give the following command:

mount /dev/hdb1 /vz/root/<veid>/var

After `vzctl start` your VE will be able to write in /var as much information, as big is hdb1 (but not /vz)

HTH,
Vasily.

But if I stop the VPS, every data will be - as in your example - on /dev/hda1, including /vz/private/<veid>/var. Or this is not as I think, and /vz/private/<veid>/var will be empty this time, because all the data it contains is on /dev/hdb1?

Right, if initially /vz/private/<veid>/var was empty, after stop of VE all data placed by VE in /var will be on hdb1 (because hdb1 was mounted on /vz/root/veid/var), and /vz/private/<veid>/var - will be empty.

Just try it Wink
