poor read speed, great write on raid10 6 disks

tngri · Sep 10, 2021

I've been able to reimport the pool so I'll be able to do the simple resilvering/replace drive test ;)
Thanks @awasb that's really cool to feel helped/followed on that issue
I think this is good to me as I'm experiencing... I felt bad about truenas on time now I feel more confident !

You are welcome!

One more thing ... Please help others to help you (just a tiny bit more than you already did) and add your hardware config to your "signature". It's within the account-settings.

Please add a spoiler, so it doesn't have that much impact on available screen size in case somebody knows your machine's specs already.

Code:

board: $MOTHERBOARD
memory/RAM: $RAM
drives: $DRIVES
power unit: $PSU
case: $CASE
etc.

You'll find more detailed advice right here:

Next level would be posting under the right category. Maybe bad read performance was (bad) news to you. But your post get's more advanced (and probably more interested) readers under "general help / performance". ;-)

Ok after resilvering, two more sata disk with sector error / smart fail even on short test. same after cable/sata port switching
I got only one more so I may order new ones because goind further... Just waiting for long smart test result on all other drivers now

I also removed the chelsio eth adapter for now, just in case, because it's hot and maybe to close from my sata cables ...

I used WD Red 4TB, I think I'll stick on them because I not sure 8TB etc are good, same heat etc... what do you think guys ?

I'd use a mix of different brands. Exos drives have been good for us.

You mixed up what I wrote about read and write. With SMB (async write by default) write speeds higher than read ones are not that uncommon.

Ho sorry I got it now sorry, no write cache with ZFS, only kind of optimisation for writing sequentially a queue of write transactions right ?

Ok some news for those who are interested or helping :)
I've ordered two IronWolf 6TB - 5400rpm, and a UPS (Eaton 3S 850).
I hope to get deliver tomorrow and install everything ...

Guess what ? this morning my Power Suffly suddently died !
I replace it with a new one I had allready for this...
Now ada4 still fail on Smart SHORT but not ada1 anymore !!!

I also realized that the fio script I used was for 4k block, when using 1024k BS it not bad at all

but reading speed are still king of 1GB limited (125MB/s shown by windows explorer dialog)

Now that the pool seems sane, did you check connection bandwidth? iperf?

Furthermore: is it direct connection or switched?

tngri · Sep 15, 2021

Direct Connection, no switch involved

Well I got some weird values (smb copy is still r/w : 120MB / 600~300MB)

Concerning block size(s):

Code:

dmesg | grep ada

and/or

Code:

smartctl -i /dev/ada0

and

Code:

zdb -U /data/zfs/zpool.cache

Concerning samba:

Code:

testparm -s

Thank you. The disks' "native" block size is 4096B and the pool's ashift=12 is correct (2^12). That's good.

Concerning your samba-output: The (usually quite interesting) global parameters are missing. Should be something like this:

Code:

Load smb config files from /usr/local/etc/smb4.conf
Loaded services file OK.
Server role: ROLE_STANDALONE

# Global parameters
[global]
        aio max threads = 2
        bind interfaces only = Yes
        disable spoolss = Yes
        dns proxy = No
        enable web service discovery = Yes
        kernel change notify = No
        load printers = No
        logging = file
        max log size = 5120
        nsupdate command = /usr/local/bin/samba-nsupdate -g
        registry shares = Yes
        restrict anonymous = 2
        server role = standalone server
        server string = TrueNAS Server
        unix extensions = No
        idmap config *: range = 90000001-100000000
        fruit:nfs_aces = No
        idmap config * : backend = tdb
        directory name cache size = 0
        dos filemode = Yes

As far as numbers are concerned, I'd wait, until the new disks are "in".

OK. No fancy multi channel / rss config. (Which hurts AFAIK when used with a spinning disk pool.) Again: good.

tngri · Sep 17, 2021

So that maybe related to the Chelsio NIC hardware or the cable ?

Important Announcement for the TrueNAS Community.

poor read speed, great write on raid10 6 disks
