This is especially important if you have multiple RAIDs connected to the system. We will need the UUID of the array to identify the harddisks. GNU Parallel - If it is not packaged for your distribution install by: The goal is to get back to state 3 with minimal data loss. This is the situation we are going to recover from. Md0 : active raid6 sdn1(S) sdm1 sdk1(F) sdj1 sdh1(F) sdg1(F) The rebuild on /dev/sdn1 cannot continue, so /dev/sdn1 reverts to its status as spare (state 4): recovery = 59.0% (60900/101888) finish=0.6min speed=1018K/secīefore the rebuild finishes, yet another data harddisk (/dev/sdh1) fails, thus failing the RAID. Md0 : active raid6 sdn1 sdm1 sdk1(F) sdj1 sdh1 sdg1(F) The rebuild on /dev/sdn1 continues (state 3): Now all redundancy is lost, and losing another data disk will fail the RAID. Md0 : active raid6 sdn1 sdm1 sdk1(F) sdj1 sdh1 sdg1 ![]() Md0 : active raid6 sdn1(S) sdm1 sdk1 sdj1 sdh1 sdg1ģ05664 blocks super 1.2 level 6, 512k chunk, algorithm 2 įor some unknown reason /dev/sdk1 fails and rebuild starts on the spare /dev/sdn1 (state 2): It starts out as a perfect RAID6 (state 1): This article will deal with the following case. 6 Making the harddisks read-only using an overlay file.
