More than this can cause kmalloc - failure. - - New 'CREATE' line in mdadm.conf for defaults such as owner, group, - mode and auto-flag - - --detail checks if array has been started or not and includes that - in report. - - When using --update=uuid on an array with a bitmap, update the - bitmap's uuid too. - - Add a copy of /proc/mdstat to the mail message sent by mdadm - --monitor. - - New flag --no-degraded to avoid starting arrays if there are - fewer devices available than last time the array was started. - This is only needed with --scan, as with --scan, that behaviour - is the default. - - Support for 'homehost' concept. This is a fairly major update. - It includes a configfile option and a command line option for - specifying a homehost, records that host in the superblock, - and reports the homehost where possible. - - Support for Auto Assembly. "mdadm -As" will, if provided with - the name of a homehost, try to assemble all arrays it can find - that were created for that homehost. See man pages for more details. - -Development of mdadm is sponsored by - SUSE Labs, Novell Inc. - -NeilBrown 26th May 2006 - |
