Hi All, We have a small test cluster that is CCR enabled. It only had/has 3 NSD servers (testnsd1, 2, and 3) and maybe 3-6 clients. testnsd3 died a while back. I did nothing about it at the time because it was due to be life-cycled as soon as I finished a couple of higher priority projects.
Yesterday, testnsd1 also died, which took the whole cluster down. So now resolving this has become higher priority… ;-) I took two other boxes and set them up as testnsd1 and 3, respectively. I’ve done a “mmsdrrestore -p testnsd2 -R /usr/bin/scp” on both of them. I’ve also done a "mmccr setup -F” and copied the ccr.disks and ccr.nodes files from testnsd2 to them. And I’ve copied /var/mmfs/gen/mmsdrfs from testnsd2 to testnsd1 and 3. In case it’s not obvious from the above, networking is fine … ssh without a password between those 3 boxes is fine. However, when I try to startup GPFS … or run any GPFS command I get: /root root@testnsd2# mmstartup -a get file failed: Not enough CCR quorum nodes available (err 809) gpfsClusterInit: Unexpected error from ccr fget mmsdrfs. Return code: 158 mmstartup: Command failed. Examine previous error messages to determine cause. /root root@testnsd2# I’ve got to run to a meeting right now, so I hope I’m not leaving out any crucial details here … does anyone have an idea what I need to do?
