Hi, syslog entries before any problems: Feb 18 19:52:53 NAS-server kernel: [ 5.755150] md/raid:md0: device sde operational as raid disk 5 Feb 18 19:52:53 NAS-server kernel: [ 5.755158] md/raid:md0: device sdb operational as raid disk 0 Feb 18 19:52:53 NAS-server kernel: [ 5.755160] md/raid:md0: device sdf operational as raid disk 3 Feb 18 19:52:53 NAS-server kernel: [ 5.755162] md/raid:md0: device sdg operational as raid disk 1 Feb 18 19:52:53 NAS-server kernel: [ 5.755164] md/raid:md0: device sdd operational as raid disk 2 Feb 18 19:52:53 NAS-server kernel: [ 5.755166] md/raid:md0: device sdc operational as raid disk 4 Feb 18 19:52:53 NAS-server kernel: [ 5.757272] md/raid:md0: raid level 6 active with 6 out of 6 devices, algorithm 2 [...] Feb 18 19:52:54 NAS-server smartd[1188]: Device: /dev/sdc [SAT], ST4000DM004-2CV104, S/N:WFN14WVT, WWN:5-000c50-0bee83a77, FW:0001, 4.00 TB Feb 18 19:52:54 NAS-server smartd[1188]: Device: /dev/sdd [SAT], ST4000DM000-1F2168, S/N:Z305RJAR, WWN:5-000c50-087ccf402, FW:CC54, 4.00 TB Feb 18 19:52:54 NAS-server smartd[1188]: Device: /dev/sdb [SAT], ST4000DM000-1F2168, S/N:Z305RFDP, WWN:5-000c50-087cd03a5, FW:CC54, 4.00 TB Feb 18 19:52:55 NAS-server smartd[1188]: Device: /dev/sde [SAT], WDC WD40EZRX-00SPEB0, S/N:WD-WCC4E7TULA48, WWN:5-0014ee-2b5d93dd9, FW:80.00A80, 4.00 TB Feb 18 19:52:55 NAS-server smartd[1188]: Device: /dev/sdf [SAT], ST4000DM000-1F2168, S/N:Z305RVDW, WWN:5-000c50-087cc5e98, FW:CC54, 4.00 TB Feb 18 19:52:55 NAS-server smartd[1188]: Device: /dev/sdg [SAT], ST4000DM000-1F2168, S/N:Z305RTB8, WWN:5-000c50-087cc9d0b, FW:CC54, 4.00 TB Isn't that quite clear how the order should be? I have added those disks to the create array in that order 0,1,2,3,4,5 Should I try something else? I was wondering if the problem is unused space? The only disk having it partition table have this: Unused Space : before=254896 sectors, after=7856 sectors So if creating a new array starts from the wrong place? Can that be somehow inspected?
