Hallo All,
we had following szenario. Gpfs Cluster with 3 nodes Node A, NodeB as role NSD-Server and Node C as quorum buster node. We wplan to update this cluster with a fourth node as a client node over nsd Server connected. The storageconfig looks like this:
mmlsdisk gpft01 -L[1@s
disk driver sector failure holds holds storage
name type size group metadata data status availability disk id pool remarks
------------ -------- ------ ----------- -------- ----- ------------- ------------ ------- ------------ ---------
d01DaMT001 nsd 512 1 Yes Yes ready down 1 system
d01DaMT101 nsd 512 0 Yes Yes ready up 2 system desc
d01DaMT002 nsd 512 1 Yes Yes ready down 3 system
d01DaMT102 nsd 512 0 Yes Yes ready up 4 system desc
d01Desc0001 nsd 512 2 No No ready up 5 system desc
Number of quorum disks: 3
Read quorum value: 2
Write quorum value: 2
The failuregroup 1 was down because of Maintenance. We changed the available nsd's of failuregroup 0 with the NSD-Server node a and b. After that we added the node d with mmaddnode. All looks fine.
But after the end of the disk maintenance we want to establisch the same nsd server list to the nsd of FG 1. Here came the problem. The establish of the same definition was only possible if i delete the fourth node, unmount the filesysten, change the nsd serverlist and go forward with readding the node again. Are there any possibility to change the nsd-serverliist online?
Thanks Renar
