[SOLVED] RAID 5 - Capacity > Available on filesystem - How resize it

Hello,

I'm new in the forum but not new with OMV, i use it from the release 3 and i migrated to the release 5 a few days ago.

OMV is installed on a Vmware ESXI Hypervisor (relaease 6.7), with 4 disks dedicated to OMV (Raw Disk Mapping - 4To each).

I identified something i want to fix:

- On Storage / RAID Management: I can see my RAID:

Version : 1.2 Creation Time : Tue Dec 20 20:46:28 2016 Raid Level : raid5 Array Size : 11720661504 (11177.69 GiB 12001.96 GB) Used Dev Size : 3906887168 (3725.90 GiB 4000.65 GB) Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Sat May 2 19:37:29 2020 State : clean Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : left-symmetric Chunk Size : 512K Consistency Policy : resync Name : openmediavault:raid UUID : d5c2f71f:a3879155:c5a1be00:a55c3e24 Events : 21966 Number Major Minor RaidDevice State 0 8 16 0 active sync /dev/sdb 1 8 32 1 active sync /dev/sdc 2 8 48 2 active sync /dev/sdd 3 8 64 3 active sync /dev/sde

My capacity is 10,92 TiB

- On Storage / File Systems :

Total is set to 7,22 TiB

I remind now that initialy, i had disks with a 3 To capacity, and i never resize it.

My question is: how can i resize it without losing my datas ? (it is not possible for me to backup all my used datas (6 To))

Thanks in advance,

Regards,

Alex

Hello,

I saw that command in the forum:

mdadm --grow /dev/md127 --size=max

Is it the same role as "resize" bottom on the interface ?

Will it erase my datas ?

Alex

Thank you for your reply.

Hi,

I launched the command an i think it is not the good one, here is the result:

root@openmediavault:~# mdadm --grow --size=max /dev/md127
mdadm: component size of /dev/md127 unchanged at 3906887168K

There is something else but i don't know what.

Regards,

Yes, it's the same:

root@openmediavault:~# mdadm --grow /dev/md127 --size=max
mdadm: component size of /dev/md127 unchanged at 3906887168K
root@openmediavault:~# mdadm --grow --size=max /dev/md127
mdadm: component size of /dev/md127 unchanged at 3906887168K

It works immediately, thank you geaves.
