Hi,
I have seen some problems with a new file system that I created
yesterday in that I could repeatedly get the system to crash in with a
mkdir.
Here is the disk information
mfid1: <MFI Logical Disk> on mfi1
mfid1: 5716992MB (11708399616 sectors) RAID volume 'Images' is optimal
I created a new file system tuned for 64k blocks, an average file size
of 1Mb, and 2500 files per directory.
newfs -b 65535 -g 1048576 -h 2500 /dev/mfid1p1
mount /dev/mfid1p1 /compere
mkdir /compere/images
mkdir /compere/images/1999
(Also tested with mkdir test; mkdir test/1998)
The system is and amd64 system running 6.2-RELEASE and the pmap.c patch.
I have 3 cores cause by 3 different apps (rsync, gmkdir, mkdir) and
can provide any more information if required. I have attached a back
trace, unfortunatly I cannot do any testing as the system is now in
testing (newfs -b 65535 -g 1048576 /dev/mfid1p1 was used and seems not
to cause the bug).
This might be simple to fix, but please file a PR if it does not get
picked up by someone on this list.
