Hi,
I want to mount CIFS storage on every node of pacemaker cluster, so I use
clone like following:
<clone id="cifs-clone">
<meta_attributes id="cifs-clone-meta_attributes">
<nvpair id="cifs-clone-meta_attributes-target-role"
name="target-role" value="Started"/>
</meta_attributes>
<primitive class="ocf" id="Mount_cifs" provider="heartbeat"
type="Filesystem">
<instance_attributes id="Mount_cifs-instance_attributes">
<nvpair id="Mount_cifs-instance_attributes-device" name="device"
value="//192.168.1.40/xxxx"/>
<nvpair id="Mount_cifs-instance_attributes-directory"
name="directory" value="/mnt/cifs"/>
<nvpair id="Mount_cifs-instance_attributes-fstype" name="fstype"
value="cifs"/>
<nvpair id="Mount_cifs-instance_attributes-options" name="options"
value="username=admin,password=xxxx,rw"/>
</instance_attributes>
</primitive>
</clone>
However when I start cifs-clone, some error occurred, start failed,
following is the log.
Dec 21 18:50:24 h10_150 Filesystem[2935]: INFO: Running start for
192.168.1.40:/mnt/test/nfs/xxxx on /mnt/nfs
Dec 21 18:50:24 h10_150 Filesystem[2935]: ERROR: DANGER! cifs on
192.168.1.40:/mnt/test/nfs/xxxx is NOT cluster-aware!
Dec 21 18:50:24 h10_150 Filesystem[2935]: ERROR: DO NOT RUN IT AS A CLONE!
Dec 21 18:50:24 h10_150 Filesystem[2935]: ERROR: Politely refusing to

Dec 21 18:50:24 h10_150 crmd: [2083]: info: process_lrm_event: LRM operation
Mount_cifs:0_start_0 (call=13, rc=6, cib-update=103, confirmed=true) not
configured
So I read the Filesystem script code, find following code before start
resource.
case $FSTYPE in
ocfs2) ocfs2_init
;;
nfs|smbfs|none|gfs2) : # this is kind of safe too
;;
*) if [ -n "$OCF_RESKEY_CRM_meta_clone" ]; then
ocf_log err "$OCF_RESKEY_CRM_meta_clone"
ocf_log err "DANGER! $FSTYPE on $DEVICE is NOT
cluster-aware!"
ocf_log err "DO NOT RUN IT AS A CLONE!"
ocf_log err "Politely refusing to proceed to avoid data
corruption."
exit $OCF_ERR_CONFIGURED
fi
;;
Esac
I want to know why CIFS isn't the kind of safe FSTYPE, but smbfs is
considered safe ? They are not the same as it ?
PS:
I could start CIFS resource directly instead of clone.

Qiu Zhigang
