[SSI-users] Debian Lenny OpenSSI with LVM and RAID 1

[Cumberland, L. <lon...@ni...>]

Hello All,

I hope that you are doing well today. I have abandoned the FreeNX idea over a much simpler one for our particular need. It uses XRDP which can be installed from apt-get (also from http://xrdp.sourceforge.net/) and as most our connection users will be coming from a Windows machine, this will make things easier. So far it works well, but I have to adjust the keymap still.

Now I am looking at the disk drives that are located on each node for mapping into a single filespace so that all space appears to be a single drive to the users. For this, I was reading that OpenSSI appears to be using DRBD (if I understand correctly) which allows it to mount the filespace on each node. If this is so then I am guessing that perhaps I could use LVM to bring all of the drives together into a volume.

If that is not possible then perhaps I am utilize a stackable files system from FUSE like XtreemFS, gfs, or some other. Any ideas?

I am also going to be adding RAID 1 to the system so that the main drive has a complete mirror and failover incase the main drive goes down then the secondary will pick up.

Thanks and have a great day,
