- Minor
Hi,
TLDR: My server crashes if i initiate large file transfers with kb to gb sizes. With or without docker enabled. Don't know what to do, any help to diagnose this would be appreciated.
As there was nearly no interaction on my "General Support" post, i'm trying it over here. The previous diagnostics (multiple) are attached to this post:
I've changed docker to ipvlan, but even without docker activated i have these crashes. This also happens since several unraid versions ago and i've switched server hardware completely in between, except for my unraid usb stick.
My main problem is, that i have no idea where to go from here and better the situation. If i don't transfer many things it runs smoothly for months. Then (as e.g. the last couple of days) i can reproduce crashes with specific operations.
Since there is no syslog entry and no error message afterwards i'm not sure why the server crashes. There is no screen to look at (everything blank) or any remote connection possible. Is there some way to see kernel panics or similar with physical monitors?
Steps i've taken (in no special order):
- Diagnosed several dockers separately
- switched to ipvlan
- switched to second network interface
- changed from fritzbox setup to unifi incl. new subnets
- changed all hardware over the years
- started completely new with my unraid config (i think on 6.10)
- disabled docker, only used rsync to transfer
- switched from standard unraid fs to encrypted fs
I don't use VM, and switched over to pure docker compose since a couple of generations of unraid. I've installed per slack package and per script on array start. No difference. Before that i used the unraid templates and had the same problems on bigger downloads.
Some things i've found interesting:
- i don't have crashed while munching files only on the server like transcoding 4k with plex
- Generating previews from a couple of thousand video files (literaly) also no problem
- after a crash i can start the server normal, start the array, let the parity check run and get no errors. Even though the server crashed on a file transfer
Any ideas?
