Hello, Ok I figured out id just try
some of the vaules from the previous post without fully understanding them, and
multipath appears to be working. dm-1 [size=546
GB][features="0"][hwhandler="0"] \_ round-robin 0
[active][first] \_ 0:0:0:0 251:0
[undef ][active] \_ round-robin 0 [enabled] \_ 0:0:0:0 251:4
[undef ][active] But I stil get an error [root@dell-1650-31 ~]# mount
-t gfs /dev/mapper/dm-1 /mnt/gfs1 mount: /dev/dm-1: can't read superblock if I do a dmsetup remove dm-1, then mount the
individual gnbds all is well, but the purpose of this is to enable some sore of
failover which I am told GNBD has the capability of doing. From redhats main site and documentation for gfs 6.1 they
state that multipath is not supported in the 6.1 realease however I optained
this source from CVS and the main docs for http://sources.redhat.com/cluster/gnbd/
state that multipath is an option. Can someone clarify whether the CVS stabile
sources for kernel-2.6.12 is multipath compatable, or am I doing something
wrong? Current specs. SAN -> MSA-1000 3 GNBD servers currently using software iSCSI to mount that
SAN – will prob go fiber if I can figure this out. ( lets say this
cluster is called cluster1) Using DLM & GNBD 1 client for testing separate cluster name lets say “cluster2” Client mounted the gnbd from one of the servers that is
exporting it, the servers are not mounting it, then formatted the device with
gfs & created 20 journals size of 32MB each, remounted the device and verified
write and read (bonnie++) Ran dmsetup to round robin the devices then failed to mount
the volume as shown above. Brian Urrutia System Administrator Price Communications Inc. |
