Keep an eye on this thread.I was impressed with gea's words regarding 11.4 beta release, so I decided to move my home NAS from FreeNAS to Solaris 11.4.
Of course, this was not an urgent need, simply because sometimes everything is boring. My job is not IT related, so it's akin to a fun hobby.
My old ZFS pool was encrypted by FreeNAS 11, so it was a trouble to decrypt it and import it to Solaris (at least i think so), so i decide to backup all data to external HDD's and build new RAIDZ2 on Solaris. I follow gea instructions, installed beta repository and installed napp-it, RAIDZ2 was build and encrypted from napp-it GUI.
64Gb ECC Reg
HBA Supermicro AOC-S2308L-L8e (only one thing i added between FreeNAS and Solaris)
So at this moment i have RAIDZ2 pool from 8x3Tb HDD, Solaris installed on 20Gb SSD, around 4Gb left.
Right now NAS connected to network switch with single 1Gb link via onboard i350 adapter.
ZFS encryption enabled.
But i have perfomance issues over SMB from my Windows 10 computers. After ZFS pool was build and i shared it, all my 8Tb of data was upoloaded over LAN from my external HDD's. Everything went smooth, sustained 115 mb/sec over 1Gbit link for few days.
But now if i copy something to NAS i get something like this:
View attachment 8803
View attachment 8804
Both images indicate ~4Gb file copy over SMB to NAS.
I do not see anything suspect at Solaris Dashboard or napp-it web GUI.
Meanwhile, if i opening MKV file from NAS in my player - i also notice ~5 sec freeze before movie start, every rewind also cause a short freeze.
I don't understand where i should start my searching..
Maybe anyone can give me any advice?
Thank you anyway.
Thank you for reply, @m4r1k.Keep an eye on this thread.
Thank you, @gea. I am trying to perform iozone 1g, but after i disabled caching it's took whole day and still "running".What you can do is to identify to problem with
- If you disable caching, any ZFS will become extremely slow as this is what ZFS makes fast despite all the security options that are only possible with a performance price. (more data due checksums, double metadata, higher fragmentation due CopyOnWrite). So disable only for some tests where you want to compare results without RAM caching influence. Under working conditions never disable.
Sorry, I meant Oracle Solaris forum, the one from the link I sent before.
It may be the Solaris web dashboard.Upd: Can't update due insufficient disk space... Probably cache or something else eat my disk space. As i wrote before - Solaris installed at 20Gb SSD, last time i check it was around 4Gb left, now only 161Mb...
