Thanks again! Unfortunately, it doesn't work reliably yet. Trying a testport with poudriere logs mounted via virtfs, I got errors like these: #v+ /usr/bin/awk: can't open file 14a-default/2022-07-15_16h43m01s/.poudriere.j= ailname input record number 1, file 14a-default/2022-07-15_16h43m01s/.poudriere.ja= ilname rename: /usr/local/poudriere/data/logs/bulk/14a-default/2022-07-15_16h43m01= s/.tmp-.poudriere.snap_loadavg.OV0Gxx2m to /usr/local/poudriere/data/logs/b= ulk/14a-default/2022-07-15_16h43m01s/.poudriere.snap_loadavg: Invalid argum= ent _mktemp: mkstemp failed on 14a-default/2022-07-15_16h43m01s/.tmp-.data.json= =2EstpmwmGg: Invalid argument mapfile_write: Missing handle #v- after that, the mount is somehow broken: # ls -l /usr/local/poudriere/data/logs/ ls: bulk: Invalid argument So, probably it's back to NFS *for now*. Still the best attempt I've seen so far, all others I tried crashed the kernel on mount ;) BR, Felix --=20 Dipl.-Inform.
