System has 2 RAID5 units, both with 4 HDDs
raid5 1: works sd(bcde)
raid5 2: offline sd(fghi)
LVM spans both raid5
hd sdf (number2 raid) has failed..
is there a way to get the second raid up and running in degraded mode, so i can take the files off from it?
i added them to:
Services -> SMB/CIFS -> Extra Options
i also followed this article:
http://www.sysprobs.com/windows-7-network-slow
specific: remove autotuning & Remote Differential Compression
also, if you have
Large Send Offload v2 -> Enabled
disable for both IPV4 & IPV6 seems to have a lot problems with throughput.
i added this to the extras section on omv, and it helped me go from 3MB/s to 11MB/s (wifi)
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
im using windows 7, so that might be where the problem is, the extra parameters that ive added does gie a good speedup which is better than before
ftp: 107 MB/s så quite fast compared to smb.
hmm i search around and found that by adding:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
i could gain some more speed, so new speed from nas to laptop wireless is now 11 MB/s which is a gain of 3 times the old value.
write speed with dd: 243 MB/s
read speed with dd: 2.1 GB/s
cpu never gets over 40% (4 core amd phenom 2.5 GHz) 16GB ram
ftp speed wireless: 12 MB/s
which is still way better than smb latest test is 3.4 MB/s from nas to laptop.
ok so i connected my labtop to my network by wire:
upload: 80MB/s
download: 20MB/s
seems wierd that its faster to store than to read...
and my harddrive is fast enough ive tested with an usb-3 disk to and from with both ways going over 100MB/s
Hi,
i have a question regarding samba performance.
connection is from my local network to my labtop running via wifi (ac speed)
when i copy a file to the NAS, i get aprox 30mb/s which is ok for wifi (could be better but anyway)
if i copy a file from the NAS, i only get aprox 3 mb/s even the same file that i copied to the nas...
this sounds strange in my ears, anyone experienced this, and have a solution?
