I have been trying to add a single mirrored disk to Open Media Vault and been getting:<\/p>\n

\"Error<\/p>\n

In my case the new disk was created using a Debian live USB disk. I think this was the problem. So I booted to OMV and looked at the mdadm config file in Debian:<\/p>\n

# mdadm.conf\r\n#\r\n# Please refer to mdadm.conf(5) for information about this file.\r\n#\r\n\r\n# by default, scan all partitions (\/proc\/partitions) for MD superblocks.\r\n# alternatively, specify devices to scan, using wildcards if desired.\r\n# Note, if no DEVICE line is present, then \"DEVICE partitions\" is assumed.\r\n# To avoid the auto-assembly of RAID devices a pattern that CAN'T match is\r\n# used if no RAID devices are configured.\r\nDEVICE partitions\r\n\r\n# auto-create devices with Debian standard permissions\r\nCREATE owner=root group=disk mode=0660 auto=yes\r\n\r\n# automatically tag new arrays as belonging to the local system\r\nHOMEHOST &lt;system&gt;\r\n\r\n# definitions of existing MD arrays\r\nARRAY \/dev\/md0 metadata=1.2 name=nas2:RAID1Mirror UUID=a77b4c17:6ddd1afc:58bf7cdd:a51275ef\r\n\r\n# instruct the monitoring daemon where to send mail alerts\r\nMAILADDR tony@cantabrian.co.nz\r\nMAILFROM root<\/pre>\n
The config file can be found at:<\/p>\n
\/etc\/mdadm\/mdadm.conf<\/p>\n
The problem I suspect was that the new disk was also “\/dev\/md0”, so I commented the line out:<\/p>\n
ARRAY \/dev\/md0 metadata=1.2 name=nas2:RAID1Mirror UUID=a77b4c17:6ddd1afc:58bf7cdd:a51275ef<\/pre>\n
Then I restarted and the new disk showed up.<\/p>\n","protected":false},"excerpt":{"rendered":"
