hi list, I recentlt setup a two server GFS cluster. Both of them export a 8G partition useing gnbd_serv and import eaother with gnbd_import. I assambled these two gnbd block to a ~17G pool. After that, I run ccs_servd at one server ( hostname: gfs1 ) to serve the ccs archive, and started the ccsd, lock_gulmd. Then I run gfs_mkfs at gfs1, and mounted the newly created fs on both servers. Everything seems ok, before I write something to the fs mounted at the other server ( hostname: gfs2 ). When I mkdir at machine gfs2, machine gfs1 can't see that directory; but when I mkdir at machine gfs1, gfs2 can see that new directory . I tried dd a 1GB file to the filesystem at machine gfs2, but at machine gfs1, I still see nothing. How can I figure out what was wrong? The /var/log/message didn't provide enough information... -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
