I'm in the testing phase w/ gfs. I have 2 nodes in a cluster which are manually fenced. I'm working on the basics, creating/removing volume groups and volumes, creating filesystsems and testing performance.
I created a 20gb volume on a 956gb lun, created a gfs filesystem on it, and mounted it on both nodes. I ran some performance tests (creating 10,000 files, removing them, tar, untar, etc.). The results looked ok and everything appeared normal. After running the tests a few times, I unmounted the fs, and tried to deactivate the volume w/ "vgchnage -aln". I got this error...
/dev/sdb: lseek 135222817456128 failed: Invalid argument
lvdisplay didn't work but vgdisplay did. I was able to mount the fs again. After umounting, I tried stopping the clvmd daemon and a few other things, and now I'm at the point where the vol group is not even found.
I can easily start from scratch, but this behavior has me concerned. Any ideas?
