Pass through of an LSI 2308 with ESXI 6.7U1 and 11.4 doesn't seem to work. System just freezes
Tried copying the mpt files from omnios 15028 and get a bunch of 'invalid kernel relocation type' messages and the driver does not load.
Any suggestions or am I out of luck with this controller?
If I am out of luck, can someone recommend one that would work?
Snapshot of the freeze by using the “-m verbose -v” after $kern on file /rpool/boot/grub/grub.cfg
I bought the IBM 1015 and cross flashed it to the LSI 92111 and all is fine. The card had worked for months in OmniOS
Everything is working better than expected. One thing I'd like to know is how I can get rid of the picket fence when writing. I tried adding write cache, but it still happens. I understand that it's a flush from memory, but I have over 550MB/s bandwidth and I am only writing at gigabit speeds
This is the effect of the writecache flush in Solaris every 5s.
Solaris collects all (small) writes in RAM for 5s and writes it then as a single large sequential write to pool. This is why performance goes to upper limit (write to RAM) and zero duting a flush to pool.
Open-ZFS (OmniOS) behaves different. There the cache is size determined, ex 4GB/ 10% of RAM. A flush to disk is initiated there when the cache is full not after a given time.
The result is that on short write peaks Solaris ZFS is much faster (ok, Solaris is mostly faster) while Open-ZFS has a more even write behaviour on a steady write load without reaching the upper limit but without the drops. The effective performance is the area covered by the graph over say your 60s.
10k write operations in 2s means around 5k per second.
You are correct that this is far above of the pool's physical capability.
A single disk can give around 100 physical io iops. A pool from 8 mirror vdevs can give around 800 write iops and 1600 read iops. Your remark about a cache drive points into the right direction. But a cache drive (L2Arc) is only for reads.
Here you see the effect of the rambased write cache. On Solaris it has a size of around 5s of writes until it is flushed as a single large write operation to disk. Your 5k write operations are mainly writes to ram.
If you enable sync without an Slog where every write commit must land on disk your write operations per second should be more in the region of the physical capability of the pool.
Not bad for predominately second hand eBay's setup , except hdds and more ram .
Filled mostly with random files, multiplied. The goal was 80 percent, but exceeded it with little bit - 18 percents free space left:
aja's disk cache disabled , zfs sync disabled ,atime off,
Wife got new camera. I'm ready
Yeh Gea thanks,
Played with the NICs drivers setting on both ends. At the Windows side the major difference made interrupt moderation from default "adaptive" to "low" and disabling the flow control . Thats the cost of under 5 percent CPU load . With other types of calculations offloaded to the CPU the load go above 10 percent and I skip them . Same with the Jumbos - the wifi and the wired LAN are in bridge - I want other devices to be able to connect to the storage and to the windows host too. Iperf3 gives me 9 Gb/s in both directions , its fine for me, I'm not jealous
About the pool filtrate - mmy next free day I will torture it with the test in conditions of 15, 10 and finally 5 percent free space.
Just wonder about the outcome . Then I will destroy the pool and create it again.
Today marks the first delivery of our "Common Build Environment" (CBE)
releases for the Oracle Solaris 11.4.
To enable us to make new features and fixes available quicker and to more systems Oracle Solaris now uses a continuous delivery model of SRU/micro releases rather than much larger minor releases every few years.
The GA release of a major or minor was historically the release intended for non-production use for developement of free/open source software, testing, proof of concept deployments. With the switch to a continuous delivery model many new features that have been added to Oracle Solaris 11.4 are not available in a release with a non-production use license.
The SRUs also contain updates to the free and open source software that is included with Oracle Solaris. The source code repository with build instructions and patches for the open source software is available on our solaris-userland GitHub repository. Some of the Oracle Solaris patches enable free/open source software to take advantage of functionality delivered after the 11.4.0 release.
How do I get the Oracle Solaris 11.4 CBE releases?
If you already have a system with Oracle Solaris 11.4.0 GA release installed (it has the pkg.oracle.com/solaris/release IPS publisher configured) then a simple pkg update is sufficient. Alternatively, if you have a local IPS repository, you can copy the CBE, and update from there.
Intial installation ISO images on the Oracle Solaris 11.4 downloads page are planned to be made available soon.
