Hi Something strange with clustat : if CS5 is launched with a valid Quorum Disk (that we can see with mkqdisk -L) and if we break the quorum disk (i.e mkfs on the device just to simulate a pb to reach the quorum disk), the clustat command always displays the Quorum Disk "Online" : #clustat Member Status: Quorate Member Name ID Status ------ ---- ---- ------ xena140 1 Online, Local, rgmanager xena141 2 Offline /dev/sdb 0 Online, Quorum Disk Note that in this case, the cluster is not at all disturbed, there are ony some messages in syslog like : qdiskd[30709]: <warning> Error reading node ID block ... but it just need to execute again a mkqdisk and no needs to stop/start again the CS, all is then working fine.
