Our solution is to use a separate LVM for each dirvsh backup. We have a little script that adds a machine to the dirvish config and automatically creates the LVM.
Every once in a while we run into an inode problem (we have a script that shows both space and inodes for a df). When I encounter one of those machines with lots of little files, I simply create a new LVM, rsync over all the data, delete the old LVM and rename the new LVM and all goes on. I have had to do this 3 times out of 56 (so far). We start with a fairly small initial parition and grow it slowly so we can discover inode running out instead of space early on (before it takes to long ot rsync). I run a monitoring program (xymon) that checks for file systems that are filling up. SO each morning, I look to see who has passed the 80% threshhold and deal with it. With 56 file systems (currently) about once or twice a week I get to increase a file system (a simple script to do this for ext3). I could do it a lot less often by simply increasing 3 or 4 of the file systems by a bigger amount, but I like keeping an eye on it (easier to see an atypical growth). -- Isaac Traxler AIX,Linux Admin Louisiana State University [email protected] High Performance Computing 225-578-1923 LONI AIX Clusters AIX, Linux Support On Tue, 14 Aug 2012, Don Gould wrote: > Date: Tue, 14 Aug 2012 01:06:30 +0000 > From: Don Gould <[email protected]> > Reply-To: Dirvish user and developer mailing list <[email protected]> > To: Dirvish user and developer mailing list <[email protected]> > Subject: [Dirvish] Opps... out of iNodes... > > After 2 years of loving dirvish I hit the 24m nodes on the disk I was > using, which I think is ext3 formated. > > Moving forward this is not idea. > > What is the best format for disks so as not to hit this issue? > > My current config is just a boring spare old box, but moving forward I'm > going to be using a spare VPS[1] on another box to do back ups. > > Server is set up with XEN with dom0 living on a raid1 disk set the LVM > pat's for each VM.
