And yes, I don't care much for diskd. Never have. My main focus is on

capable of using aufs...
I followed your advice and changed to aufs but aufs has serious problems too
firstable, after unclean reboot swap.state grows until disk is full and
squid dies, so same problem as diskd, only in messages appears until it
dies something different:

swap.state grows and grows until disk is full and squid dies
but it get worse because without any visible reason aufs starts wiping out
cache subdirs until it is nothing left on the disk. This case has nothing
to do with the unclean shutdown problem. The following takes place on a
running machine without any visible trigger, no reboot, no error neither
form the OS or squid but this:
storeSwapOutFileClosed: dirno 0, swapfile 0009FC83, errflag=-1 (2) No such
file or directory
storeDirClean: WARNING: Creating /c/c2/63/52
storeDirClean: /c/c2/63/52: (2) No such file or directory
storeDirClean: WARNING: Creating /c/c1/0A/02
storeDirClean: /c/c1/0A/02: (2) No such file or directory
storeSwapOutFileClosed: dirno 0, swapfile 0009FC83, errflag=-1 (2) No such
file or directory
storeSwapOutFileClosed: dirno 0, swapfile 0009FC85, errflag=-1 (2) No such
file or directory
and to answer your upcoming questions, hardware is 100% ok, this are SMP
machines running freebsd releng_6 amd64
"wipe_out" starts on all cache_dirs (look at the attached images)
aufs was running for a week (after your advice) until it happened, some
weeks before on diskd, and before months diskd with 2.5-S14-20060721
same problem on 3 server
I went back to diskd and 2.5 now
but what kind of evil advice you gave me here :)
