Hello,
first I'm sorry for that english, I'm wondering if it's ok to write in german here?
Ok, so i've got a problem with my NAS.
I'm using a HP micoserver Gen8 with following config:
- 3x WD Green 2TB (Raid 5 created with OMV)
- 32GB SSD (OMV System)
- Mico SD for GRUB Bootloader
OMV:
- No Plugins inatalled
- No shared folders
- SMART active
I created an ext4 filesystem on the raid.
If I mount the filesystem, there is a permanently data transfer on the HDD's, nearly all 5secs there is a "click" on the hard drives (HDD LED blinks up too).
So the Disk aren't able to go in spin down. I don't realy know much about debian, so thats what i've done:
- Made an manual spin down : ( hdparm -y /dev/sdc ) : HDD immediately Spins up again
Without a file system manual Spindown is possible, HDDs spinning up when the Web GUI is used.
- Use IOtop to find out what's goning on.
I've read abput that process but the only thing I found out, that the jbd2 is used by many other processes.
HDD Spindown is realy important for me.
Can anyone help me?
Best Regards
Dirk
