Created attachment 1112946 [details] Extract from evm.log with debug logging enabled Description of problem: I have a RHEL7 VM that contains an ext4 formatted /boot and xfs formatted /. The VM is on RHEV 3.5.6.2, on an iSCSI Storage Domain. Running a SmartState Analysis on this fails with "No root filesystem found" Version-Release number of selected component (if applicable): RHEV 3.5.6.2-0.1.el6ev CFME 5.5.0.13 How reproducible: Every Time Steps to Reproduce: 1. Create a RHEL7 VM with ext4 /boot partition and xfs / partition 2. Run SmartState Analysis against this VM 3. Actual results: failure Expected results: success Additional info: Extract from evm.log with debug logging enabled is attached
Inspecting the environment it seems / is on the ext4 partition but the linux mount probe is failing to detect the fs. It is reporting that the /etc/fstab file cannot be found: 161101 [----] D, [2016-01-27T19:26:56.619537 #24238:51d998] DEBUG -- : MIQ(FsProbe-getFsMod) FS probe attempting [Ext4Probe] for [root] [partition: 0] 161102 [----] D, [2016-01-27T19:26:56.619637 #24238:51d998] DEBUG -- : Ext4Probe >> dobj=#<MiqDisk:0x00000008c9b190> 161103 [----] D, [2016-01-27T19:26:56.619950 #24238:51d998] DEBUG -- : Ext4Probe << TRUE 161104 [----] I, [2016-01-27T19:26:56.620005 #24238:51d998] INFO -- : MIQ(FsProbe-getFsMod) FS probe detected [Ext4] for [root] [partition: 0] 161105 [----] D, [2016-01-27T19:26:57.203389 #23968:c9b990] DEBUG -- : MIQ(MiqServer#monitor_servers_as_master) Checking other servers as master server 161106 [----] D, [2016-01-27T19:26:57.210494 #23968:c9b990] DEBUG -- : MIQ(MiqRegion#lock) Acquiring lock on MiqRegion::1000000000001... 161107 [----] D, [2016-01-27T19:26:57.213161 #23968:c9b990] DEBUG -- : MIQ(MiqRegion#lock) Acquired lock 161108 [----] D, [2016-01-27T19:26:57.326107 #23968:c9b990] DEBUG -- : MIQ(MiqRegion#lock) Releasing lock 161109 [----] I, [2016-01-27T19:26:57.733245 #24190:a55988] INFO -- : MIQ(ManageIQ::Providers::Redhat::InfraManager::EventCatcher::Runner#process_event) EMS [rhevm01.bit63.net] as [admin@internal] Skipping caug 161110 [----] D, [2016-01-27T19:26:58.376985 #24238:51d998] DEBUG -- : MIQ(MountManagerProbe-getRootMod) Mount Manager probe attempting [WinMountProbe] 161111 [----] D, [2016-01-27T19:26:58.377957 #24238:51d998] DEBUG -- : WinMountProbe << FALSE because file system (Ext4) is not supported 161112 [----] D, [2016-01-27T19:26:58.378054 #24238:51d998] DEBUG -- : MIQ(MountManagerProbe-getRootMod) Mount Manager probe attempting [LinuxMountProbe] 161113 [----] D, [2016-01-27T19:26:58.379400 #24238:51d998] DEBUG -- : LinuxMountProbe << FALSE because file /etc/fstab does not exist The file seems to exist on the vm so why this is the case is still a question.
Mo is / on an EXT4 file system? Is the description incorrect in stating it's XFS? Is there an XFS file system on the VM? Hui found a bug in out EXT4 code that could result in this problem, but that's probably not the case if root should be on XFS.
Yes, this bug was misreported, / is EXT4 and /boot is XFS on the vm in question.
