RN31600 and RAID1 with 5 disks
Hello all. I just bought a RN31600 and need to use it with 5 disks in RAID1 mode. However, as long as i put more than 2 disks in, the option only allows to create raid5 or raid6 with my 5 drives. I...
Creating a RAID1 on 5 HDDs is possible from SSH though.
Don't know if I should advise that, it depends on your experience in Linux systems.
I tried it on my unit and it worked:
## Switch to Flex-RAID from GUI ## Destroy the current volume from GUI (obviously, this wipes all data there is on it) # mdadm --create --verbose /dev/md127 --level=mirror --raid-devices=5 /dev/sd[a-e]3 [...] # cat /proc/mdstat Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md127 : active raid1 sde3[4] sdd3[3] sdc3[2] sdb3[1] sda3[0] 483536832 blocks super 1.2 [5/5] [UUUUU] [>....................] resync = 1.4% (6895616/483536832) finish=114.8min speed=69136K/sec # mkfs.btrfs -L `hostid`:data /dev/md127 [...] # mount /dev/md127 /data mount: mount point /data is not a directory # ls -al /data lrwxrwxrwx 1 root root 9 Apr 18 03:50 /data -> /dev/null # rm /data # mkdir /data # mount /dev/md127 /data # mount | grep md127 [...] # df -h [...] ## Check that volume is seen from GUI ## Reboot gracefully from GUI to finalize procedure (so ReadyNAS OS mounts everything it needs,
Thank you very much for your information jak0lantash .
I will then indeed use RAID6 !
cheers
Hi,
in the first post you wrote "and bring one outside of the office", with RAID1 in teory the disk has all data of the other, but if you use RAID5/6 the disk is not useful for retrieve data.
If you need a copy of the data offsite you must search another method.

oh wow, I can't believe I missed that point!
cs_giuseppe, you're absolutely right!
RAID6 does NOT allow to do what op is trying to achieve
I was arguing about RAID levels, and completely forgot about it, so sorry
