To change the module permanently, you can unmount the filesystem on all nodes and run the commands: gfs_tool sb <device> proto <module> gfs_tool sb <device> table <table> If it's just a temporary thing, you can unmount the filesystem on all nodes and mount with options to override the defaults in the superblock: mount -o lockproto=<module>,locktable=<table> <Module> is whatever you'd have for gfs_mkfs' -p and <table> is whatever you'd have to gfs_mkfs' -t. Note that you need to be careful when you do either of these things. Running a mixed cluster where some machines are locking a FS with one protocol/table and other machines are locking the same FS with a different protocol/table is bad. It is bound to end in great sadness. -- Ken Preslan <kpreslan@xxxxxxxxxx>
