When the new offset is earlier than the old offset, the number of devices in the array cannot shrink. When it is after the old offset, the number of devices in the array cannot increase. When creating an array, --data-offset can be specified as variable. In the case each member devi...
RAID 0 arrays cannot have spare drives because there is no chance for a spare to rebuild a damaged RAID 0 array. You must add the new device at the same time that you grow the array. First, find out the current number of RAID devices in the array: ...
Re: mdadm: fail to stop array /dev/md0: Device or resource busy ok, ive found some more info.in the XDC manual it says "Earlier versions of Serviceguard supported MD as a multipathing software". So - before XDC was born MD is supported with Serviceguard on Red...
Build an array that doesn't have per-device superblocks. For these sorts of arrays,mdadmcannot differentiate between initial creation and subsequent assembly of an array. It also cannot perform any checks that appropriate devices have been requested. Because of this, theBuildmode should only be us...
