While messing around with some of my disks, I had the misfortune of running mkswap on /dev/md2 (my root partition). It's supposed to be reiserfs. I'm making a backup of my data now just in case. The drive seems to be fine now, but I'm afraid to unmount and/or reboot. Is it safe to reboot? Do I need to run mkreiserfs and/or reiserfsck? What do I do?

Tried the same on two test installations running in vmware virtual machines.

Root partition ext3: fatal results.

Root partition reiserfs: rebooted without any errors and works.

It doesn't mean that it is safe to reboot, but perhaps gives you some indications.

Good to know. Did you use RAID1 arrays in the installs? Would that even have any effect on the situation?

I'm almost done backing everything up - I may just try rebooting and see how it goes.

It's a simple virtual machine install that I used for testing. VMWARE simulates SCSI disks, but it shouldn't matter in this case.

Just rebooted and had no problems. Moral of the story: use ReiserFS.

Thanks for your help.
