Hello drbd experts, I have drbd-8.2.6 working fine in dual-primary mode, mirroring 2 nodes. According to drbd howto (http://www.drbd.org/users-guide-emb/s-gfs-create.html) i saw that since DRBD does not support more than two nodes i can't format /dev/drbd0 using more then 2 journals (2 nodes): mkfs -t gfs -p lock_dlm -j 2 /dev/drbd0 and MOUNT IT on more then 2 nodes. Now, supposing that: - i have 4 machines grouped two by two in order to get two different drbd devices /dev/drbd0 and /dev/drbd1 - i am exporting /dev/drbd0 and /dev/drbd1 using iSCSI to the 5th macine - on the 5th machine, i am using lvm to join /dev/drbd{0,1} in one volume pvcreate /dev/drbd0 /dev/drbd1 vgcreate myvg /dev/drbd0 /dev/drbd1 lvcreate ... mylv myvg -> will result logical volume /dev/myvg/mylv Let say that /dev/myvg/mylv is exported now to another 3 nodes (again, via iscsi for example). Question: Can i use now mkfs.gfs -p lock_dlm -j 3 /dev/myvg/mylv in order to have GFS on top WITH 3 JOURNALS and of course to write on it from those 3 MACHINES AT THE SAME TIME? If not, is any other way to achieve -j 3 ...? Regards, Alx
