Scenario = you have wrongly initialize a new HDD a single disk but you would like to be added as RAID1 disk.<\/p>\n
QNap support team suggested to remove all partition and reboot NAS<\/p>\n
This should be done connecting the second disk to a computer, delete volume and partition, and connect disk back into the NAS, which is quite boring.
\n
\nHere is how to delete partition table:<\/p>\n
Check which disk is used as RAID to avoid a \u201cwrong\u201d delete So we need to clean the \/dev\/sdb partitions Dismount the volume before starting the work So we have 4 partition, type the follow to enter in fdisk mode If you need help type \u201cm\u201d<\/p>\n List all partition as above, type \u201cp\u201d Press \u201cp\u201d to delete partitions and the number of partition to delete Command (m for help): d Command (m for help): d Command (m for help): d Print all partitions of the disk with \u201cp” Device Boot\u00a0Start\u00a0End\u00a0Blocks\u00a0Id\u00a0System<\/code><\/p>\n Save the changes with \u201cw\u201d<\/p>\n You need to save RAID settings information in the \/etc\/config\/raidtab file<\/p>\n Change raidtab file like this one Change also \/etc\/storage.conf file filesystem = 104 Scenario = you have wrongly initialize a new HDD a single disk but you would like to be added as RAID1 disk.
