[Linux-cluster] question about creating partitions and gfs

[Jason]

yes, both boxes are connected to the storage, its a dell powervault 220S
configured for cluster mode. 

[root at tf1 cluster]#  fdisk -l /dev/sdb

Disk /dev/sdb: 146.5 GB, 146548981760 bytes
255 heads, 63 sectors/track, 17816 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/sdb1             1      2433  19543041   83  Linux
[root at tf1 cluster]# 

[root at tf2 cluster]# fdisk -l /dev/sdb

Disk /dev/sdb: 146.5 GB, 146548981760 bytes
255 heads, 63 sectors/track, 17816 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/sdb1             1      2433  19543041   83  Linux
[root at tf2 cluster]# 


so both sides see the storage.  

on tf1, I can start ccsd fine, but on tf2, I cant, and I see
May  8 22:00:21 tf2 ccsd: Unable to open /dev/sdb1 (/dev/raw/raw64): No such device or address 
May  8 22:00:21 tf2 ccsd: startup failed
May  9 20:17:21 tf2 ccsd: Unable to open /dev/sdb1 (/dev/raw/raw64): No such device or address 
May  9 20:17:21 tf2 ccsd: startup failed
May  9 20:17:30 tf2 ccsd: Unable to open /dev/sdb1 (/dev/raw/raw64): No such device or address 
May  9 20:17:30 tf2 ccsd: startup failed
[root at tf2 cluster]# 

in the logs
