I don't know if this _particular_ piece of information came through the list so I'll mention it. If you are using Daniel's repository for a system that you built awhile ago you should edit your /etc/yum/repos.d/fedora-updates.repo file and add yum to the exclude line.

Re: [Vserver] clean-up hash directory
My thanks to Corey and Daniel. This explains a lot. I love the vserver
incantations but really like it when I know what they are doing instead
of having to treat them as magic.
My thanks to all those that make Linux-Vserver such a great tool.

these commands should do the job. well, technically this just lists

You could easily eliminate the grep by using -links 1 in the find command.
thanks. guess i didn't see that in the man page (and i've never had reason
to mess with hardlinks before, especially using find).
to delete those listed files, add to the end:
| while read FILE; do rm -f ${FILE}; done
Would be far more efficient to use -print0 | xargs -0 rm -f.
correct, but that would have required me to offer two commands:
- one for calculating total size of all orphaned hardlinks (people, me
included, like to see the effects of what they are doing quantified for
purposes of justification and "warm fuzzies")
- another for deleting orphaned hardlinks
not an issue for me or hopefully most people, but i wanted to keep my
instructions as simple as possible (and just adding another piped command
is easiest as it simply builds upon what was already instructed). i try to
keep it KISS (Keep It Simple, Stupid) when dealing with people (the entire
mailing list) of unknown experience levels.
of course, also make sure you don't have a file in the current directory
named the same as the total size (in bytes) of all the orphaned hardlinks
or that file will be deleted (as it is the last line printed by awk), but i
didn't worry about that as the statistical odds are pretty low. when i sent the
email i wondered if anybody was going to reply noting that, so i already
had this response ready. :-D
so yeah, my suggested commands are not "production quality". ;-)
Did you hear anything on this? I ran the query on a 12+ guest system (
all FC5 ) and it ran for well over a couple of minutes before I got
tired of watching the output. This leads me to think I've got lots of
orphans. I'd like to get rid of them ( Save the inodes! ) but want to
understand what I'm doing first. Rather not fubar a live system.
This should be a perfectly safe command, I always run some cleanup after
hashifying my guests.
i hashify my guests daily as part of a daily-maintenance cron job as i
often forget after installing/upgrading a package and my vserver is not too
heavily loaded. i might toss this in there too.
I'm not sure I fully understand how vhashify works. Where are the
actual files located. Are the entries in
/etc/vservers/.defaults/vdirbase/.hash/
links to the actual files and then each guest links to these -- links?
Those would be the actual files (the file in the .hash directory is
created by vhashify as a copy of the file it's hashifying), and vhashify
then creates links to those in the guest(s).
roderick, if daniel's explanation is too succinct for you, i can reference
a few of my prior postings where i ramble on forever trying to stumble
through my own hypothesizing of how hashifying works. ;-)
