Hi,
Since last week, I'm trying to use XFS Project Quota feature. My server has
crashed two times.
I'have the same server using XFS with exactly same
configuration/version/hardware without project quota enabled. This server
run nice since 1 month
When my server crash, one directory becomes unabled. I can't acces to it. I
can't find any error. No error reporting in /var/log/syslog, /var/log/dmesg
or /var/log/kern.log
I find the process with command lsof, but can't kill it.
All other directories are avaibled
Example: if directory /a/b/c freeze:
Clic with Samba on directoy failed (waitting long time, next Windows
says server doesn't reply only on this directory)
ls /a/b/c --> Ok
vdir /a/b/c --> failed (frozen. CTRL + C don't work. Not possible to
kill process "vdir")
getfacl /a/b/c --> failed (frozen. CTRL + C don't work. Not possible
to kill process "getfacl")
ls /a/b/c/d --> Ok (I can read subdir with this command)
iotop --> Traffic on my disk not busy
htop --> CPU or RAM not busy
ps aux | grep /a/b/c --> process flag "D" (so can't be killed -->
kill -9 no = effect)
