df -h
/dev/xxxxx 813G 7.1G 741G 1% /export
df -i
/dev/xxxx 853004856 7422014 777342454 1% 328978 148072812 0% /export
~330k files. Size mostly about ~20-30 kbytes.
If i run dump -L (which creates snapshot) it runs for ever (machine doesn't respond even after 30-40 minutes). If i unplug power cable and turn on my machine again, then this filesystem will be checked by fsck and if background_fack in rc.conf is "YES", fsck will create snapshot and machine will boot, but after 2-3 minutes (background fsck starts 60 seconds after system boot) machine stop responding.
If i issue simple ls command it just hangs. You cannot even ssh to machine, becouse event network system stops responding.
Disks were formatted on a clean 5.0-RELEASE using sysinstall (using -O2 newfs option) during system installation and system was upgraded with cvsup/make build/installworld to 5.1-RELEASE
Maybe this is an issue and i should reformat my disks and everything will be fine again?
I have this problem on two machines. The third one with about 200k files boots okay, but this one was installed cleanly with 5.1-RELEASE.
