>I'm not use what you mean. The suspension of I/O during creation of a >snapshot is the intended behaviour, but it doesn't take long. For = example, df -h=20 /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. Brane
