Hi Scott, Ummm, you can still access the files inside of ploop-based container when it isn't running... simply by mounting it. Is there an issue with that? Granted: It's probably more of a psychological or philosophical issue than a technical one. Filesystem on a filesystem. That adds a

I will certainly take a look at the iostats and see if that will help. I was tasked with doing this to find a user(s) that are chewing through the ssd disks on one particular node. So I figured finding out who was doing all the writes might help figure that out, and seemed to be until today and

Re: [Users] ioacct weirdness?

Just one thing -- ioacct accounts on a VFS level, not on actual disk I/O level. Also, ioacct accounts all reads and writes, including tmpfs and /proc and /sys etc. Say, if you rewrite a file (a real file on disk) a thousand times real quick, it does not mean the data will be written to a disk

Hi Scott, vzctl has a convert option. Oh? Nice. That must have slipped right by me. Thanks for pointing that out. It seems like your argument is basically, because it was already there and people don't have to learn anything to use them. While that is true, it doesn't sound too compelling
