http://bugzilla.suse.com/show_bug.cgi?id=925564 Bug ID: 925564 Summary: [ocfs2-tools] mount fail by using "LABEL=" parameter on remote nodes Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: x86-64 OS: openSUSE 13.2 Status: NEW Severity: Normal Priority: P5 - None Component: High Availability Assignee: lmb@suse.com Reporter: zren@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- In my 3-nodes(n1,n2,n3) cluster, mount always fail by using "LABEL=" parameter on remote nodes, except for the node(n1) I mkfs.ocfs2 on. To make it easy to talk, call n1 local node, and call n2 and n3 remote nodes. After mkfs.ocfs2 on n1, it's ok to mount by "LABEL=" options on n1. But when doing the same on remote nodes, it complaints this msg: "mount: can't find LABEL=multi-write_append_truncate-test". However, when debugfs.ocfs2 -> open /dev/sdb1 -> stats, you can actually see this LABEL. But using devicename in place of LABEL, mount can succeed. I encounterd this issue when I run ocfs2 testsuites on multi-nodes. It always interrupt test. If more info or helps needed,please feel free to tell me. --------------- Reproduce steps: 1.setup cluster environment n1:~ # crm configure show ``` node 318951192: n3 node 318951194: n2 node 318951229: n1 primitive p_dlm ocf:pacemaker:controld \ op monitor interval=60 timeout=60 \ meta target-role=Started primitive p_o2cb ocf:ocfs2:o2cb \ op monitor interval=60 timeout=60 \ meta target-role=Started primitive p_ocfs2 Filesystem \ params device="/dev/sdb1" directory="/mnt/shared" fstype=ocfs2 options=acl \ op monitor interval=60 timeout=60 \ meta target-role=Stopped primitive p_stonith_sbd stonith:external/sbd \ params sbd_device="/dev/sdc1" \ meta target-role=Started group g_base p_dlm p_o2cb clone cl_base g_base \ meta interleave=true property cib-bootstrap-options: \ dc-version=1.1.12-1.1.12.git20140904.266d5c2 \ cluster-infrastructure=corosync \ cluster-name=cluster \ last-lrm-refresh=1422851544 ``` 2.mkfs on n1, and mount succeed by "LABEL" options n1:~ # /usr/bin/sudo -u root /sbin/mkfs.ocfs2 --fs-features=sparse,unwritten,inline-data --cluster-stack=pcmk --cluster-name=cluster -b 512 -C 4096 -L multi-write_append_truncate-test -N 3 -F /dev/sdb1 ``` mkfs.ocfs2 1.8.2 On disk cluster (pcmk,hacluster,0) does not match the active cluster (pcmk,cluster,0). mkfs.ocfs2 will not be able to determine if this operation can be done safely.
