I added some tunables and may have fat fingered something because after reboot, some critical function seems to have gone sideways, most notably SSH, HTTP and SMB are not functioning. The server pings and I can get console access through the IPMI. What I see from the boot messages is that the web server, ssh, etc. are failing due to "no buffer space available" (probably because I put something in the tunables that I shouldn't have!).
These are the tunables I applied:
net.inet.tcp.recvspace= 4194304
net.inet.tcp.sendbuf_inc = 2097152
net.inet.tcp.sendbuf_max = 16777216
net.inet.tcp.sendspace = 4194304
net.isr.bindthreads = 1
net.isr.maxthreads = -1
Maybe I added too many buffers?
I also made some changes to the SMB conf on the shares but I don't think that would be blowing everything out of the water like this.
Question is how do I reverse the above tunables from the shell (without the web UI)?
Setup is as follows:
Truenas Core 12.0-U6
Asrock Rack ROMED8-2T, AMD EPYC 7251, 128GB DDR4-3200, LSI 9300-8i
2x Samsung 870 EVO (boot, mirrored)
2x Sabrent Rocket 4TB NVME M.2 (wip, mirrored)
6x Ultrastar 18TB (library, vdev 0, raidz2)
7x Ultrastar 14TB (library, vdev 1, raidz2)
