[Ocfs2-devel] Fwd: RES: [Ocfs2-users] How do I resize Ocfs2 filesystem using Pacemaker stack?

[Larry Chen]

Hello Carlos,

Could you please provide the command line used to format

the partition?

I found this prompt comes from code of o2cb stack.

Unable to access cluster service while closing device
"/dev/mapper/storage1-part2"

Thanks,
Larry
