My Chunk Size is 512K .

I created the raid 5 via webgui , because when I give the command

root@Kymera:~# mdadm --create /dev/md0 -e 1.2 -n 4 -c 128k -l 5 -N Storage /dev/sda /dev/sdb /dev/sdc /dev/sdd
mdadm: invalid chunk/rounding value: 128k

not work

This is my current raid5

I have not yet created the file system

I created the raid via Web Gui , is possible the guide step by step , to follow this guide the raid must be degraded mode ?

Many Thanks

before following this guide , I have to create the raid5? :roll:

ok I destroyed my raid ,

mdadm /dev/md127 --fail /dev/sda --remove /dev/sda

mdadm /dev/md127 --fail /dev/sdb --remove /dev/sdb

mdadm /dev/md127 --fail /dev/sdc --remove /dev/sdc

mdadm /dev/md127 --fail /dev/sdd --remove /dev/sdd

Now what I do?

Does your raid already exist before you try the mdadm command?

Yes my raid already exist .

Thanks for info , I can get the command to destroy my raid?

Hello , the file system EXT4 it is better to file system XFS ?

my system is not only for storage (VM,Web Server,Proxy,NFS,Rsync (from a QNAP NAS) , I'm a little confused EXT4 or another file system ?

Zitat von "Wvrent"

Aha! There was my problem. I was assuming amd64 for for AMD only cpus, and i386 for Intel. I kept trying to find an Intel x64 image. XFS now works fine.

there is openmediavault x64?

Yes , before copying the data I do Tuning ext4 on RAID , I think it is not difficult

Ok , thanks . I think it's the best way the file system EXT4 :ugeek:

Hello , i have a new Hard Disk , 4x3TB (WESTERN DIGITAL Caviar Red WD30EFRX 3.5) which file system do you recommend for RAID 5 ?

Hello , I decided to buy a ssd for my NAS/Server (OCZ Vertex OCZ VTX3-25SAT3-60G ) , I use it only for OS (Openmediavault)

Anyone have experience with this SSD ? is compatible with OMV ?
