Igor, Thank you for your response.But I may have different idea, I have permission and ownership checked and problem still there.My team mate all have this problem for this version. this log:

return self.runExternally(func, *args, **kwds) File "/usr/share/vdsm/storage/

processPool.py", line 64, in

runExternally return self._procPool.runExternally(*args, **kwargs)

and for some reason it runs the “vgs“ cmd which should not run and failed,have not running to the "validate path" function. 10:51:58,789::lvm::287:: Storage.Misc.excCmd::(cmd) '/usr/bin/sudo -n

Guys,

Tried create StorageDomain in vdsm-4.9.4-0.18 with following parameters: sddef = '{ "id": "1ef32ac7-1e12-4823-8e8c-8c887333fe46", "type": "LOCALFS", "class":"Data", "version":"0", "name": "Test Domain", "remotePath": "/var/lib/vdsm/storagetmp1" }'

and the Path "/var/lib/vdsm/storagetmp1" is newly created

Things goes well in vdsm4.9.0 but doesn't work in vdsm4.9.4, The error message is: StorageServerAccessPermissionError: Permission settings on the specified path do not allow access to the storage. Verify permission settings on the specified storage path.: 'path = /rhev/data-center/mnt/_var_lib_vdsm_storagetmp1'

I verified all access permission and make sure it is right.Trace is below: File "/usr/share/vdsm/storage/task.py", line 863, in _run return fn(*args, **kargs) File "/usr/share/vdsm/logUtils.py", line 38, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/storage/hsm.py", line 1929, in createStorageDomain domClass, typeSpecificArg, storageType, domVersion) File "/usr/share/vdsm/storage/localFsSD.py", line 66, in create cls._preCreateValidation(sdUUID, mntPoint, remotePath, version) File "/usr/share/vdsm/storage/localFsSD.py", line 39, in _preCreateValidation validateDirAccess(domPath) File "/usr/share/vdsm/storage/storage_connection.py", line 40, in validateDirAccess getProcPool().fileUtils.validateAccess(dirPath) File "/usr/share/vdsm/storage/processPool.py", line 53, in wrapper return self.runExternally(func, *args, **kwds) File "/usr/share/vdsm/storage/processPool.py", line 64, in runExternally return self._procPool.runExternally(*args, **kwargs)

the following cmd caused this failure according to my log: CP Server Thread-18::DEBUG::2012-02-27 10:51:58,788::lvm::352::OperationMutex::(_reloadvgs) Operation 'lvm reload operation' got the operation mutex CP Server Thread-18::DEBUG::2012-02-27 10:51:58,789::lvm::287::Storage.Misc.excCmd::(cmd) '/usr/bin/sudo -n /sbin/lvm vgs --config " devices { preferred_names = [\"^/dev/mapper/\"] ignore_suspended_devices=1 write_cache_state=0 disable_after_error_count=3 filter = [ \"a%35000c500382d9c53%\", \"r%.*%\" ] } global { locking_type=1 prioritise_write_locks=1 wait_for_locks=1 } backup { retain_min = 50 retain_days = 0 } " --noheadings --units b --nosuffix --separator | -o

since I use "LOCALFS" ,I think it should have nothing to do with lvm and I have no vg in my env.This log makes me confused.Will somebody pls take a look and help with it? Thank you in advance!

You are right it's unrelated to lvm. You problem is probably ownership and/or permissions of your target folder "/var/lib/vdsm/storagetmp1". Your target should be own by vdsm:kvm with 'rwx' permissions. Actually it a little bit odd to create storage domain under /var/lib, it's not a proper place for this. Try to use something like /data/...

Regards, Igor
