Thank you.
Any suggestions regarding the loadavg and throughput?

update:

changing the LUN properties to write-back worked via config.xml, altough I don't know if that is the healthy, recommended way?
however, the loadavg is still to high and the throughput only half of the possible speed.

Hi.

On a OMV machine with some 5yo xeon and Raid5 over 11 disks, OMV sends"high loadavg" notfications when I start copying stuff to the iscsi target. Also, the write speed drops from (an unrealistic) 300mb/s to 50mb/s after ca. 30s. (1g Link)
When I want to edit the LUN settings from write-through to write-back, I get this error message:

thx.
having the -p option twice is no problem as it is described this way in the man page. /offtopic
will try and give feedback.

please?

sorry, had other things to do...

the "script" is just

#!/bin/bash
nohup ./gatling/gatling -S -p 8080 -u nobody -c /media/c805dea0-2b6d-4567-90b0-953c27be391a/foldername -P2M -f -p 2121 -a&

it starts the executable with a few parameters such as port numbers, the executing user and the path to be shared.

hi,

just put a startgatling.sh (to start an alternate webserver - gatling - besides the omv apache) into /etc/init.d/
after

update-rc.d startgatling.sh defaults

i got

update-rc.d: using dependency based boot sequencing
insserv: warning: script 'startgatling.sh' missing LSB tags and overrides
insserv: There is a loop between service openmediavault-beep and startgatling.sh if stopped
insserv: loop involving service startgatling.sh at depth 2
insserv: loop involving service openmediavault-beep at depth 1

which in general says i'm not experienced with linux at all, just copying commands from all over the internet and being overwhelmed when it actually works

can anyone help?

another problem with fs/mount points

- raid5 on 5 disks, one single mount point using whole md0
- wanted to test iscsi -> unmounting mountpoint not possible
- unmounted mount point manually, shrinked md0 with e2fsck and ext2resize
- webgui: filesystems: create mount point -> not possible, no volume to choose from

But something is not very useful:
Forcing the kernel to release all buffer caches, so that the memory is nice and green and empty ... :?

(first post here)
i use omv just as a "data grave" where i put up stuff from time to time, therefore quick answer times are not as important as in a business server environment. i recognize higher power consumption of my nas (former desktop pc with 5 old hdds in raid5, 2gb ram) after i moved some data to omv, compared to the "empty" state of the ram just after booting - also after spindown. is there a way to carefully clean up the ram after a certain time?
cheers.
