Hi, Have problem with creating VDI on local SR type=ext xe vdi-create sr-uuid=ba4e9e1a-bc42-0dc9-af0e-5db2905666ab name-label=test sharable=false type=user virtual-size=100MiB Error code: SR_BACKEND_FAILURE_78 Error parameters: , VDI Creation failed [opterr=error 127], xapi: [20120325T14:50:58.472Z| info|hyperion|60835 UNIX /var/lib/xcp/xapi|VDI.create R:e2cdeb6b186d|audit] (''trackid=51bd7a4a8b299b312f6f958f5d370a1c'' ''LOCAL_SUPERUSER'' ''root'' ''ALLOWED'' ''ERROR:SR_BACKEND_FAILURE_78: [ ; VDI Creation failed [opterr=error 127]; ]'' ''API'' ''VDI.create'' ((''name_label'' ''test'' '''' '''') (''name_description'' ''<value/>'' '''' '''') (''SR'' ''Local storage'' ''ba4e9e1a-bc42-0dc9-af0e-5db2905666ab'' ''OpaqueRef:676707ab-b93a-6e91-8824-dce326928452''))) There is no such problem when create VDI on Local SR type=lvhd. Both tests are made with sr created on the same physical partition xe sr-create host-uuid=5fbdc200-4165-f850-3e7a-2ab1d00a2221 content-type=user type=ext device-config:device=/dev/sda3 shared=false name-label="Local storage" name-description="Local storage" sm-config:allocation=thin and xe sr-create host-uuid=5fbdc200-4165-f850-3e7a-2ab1d00a2221 content-type=user type=lvhd device-config:device=/dev/sda3 shared=false name-label="Local storage" name-description="Local storage" sm-config:allocation=thin There is no problem creating VDI on lvhd local SR, but when try same operation on ext local SR it always failed. Ext partition is mounted properly and accessible RW through /run/sr-mount/{sr uuid} mount point. Xen version 4.1.2 (Debian 4.1.2-2.1) XCP-XAPI toolstack 1.3.2-1 Anyone managed to work around this problem ? Regards, Dimitar Kazakov
