Hi, [cc'd to arm@ and fs@ where it's also relevant] I have a number of rpi3 & rpi3 machines. Usually I want to attach a usb keydrive to them so that the sdcard isn't thrashed. They're all running -current. usr/src and usr/ports at least are mounted on the keydrive.
When initially updating eg the ports tree, svn will time out/crash because of the poor write performance of these devices in a rpi2/3 context. The fs on the usb keys is always ufs2. I have tried mounting these devices as -o async and also in fstab but this parameter seems not to 'take' in that mount doesn't report the async property set: [...] /dev/da0p2 on /ext (ufs, local, noatime, soft-updates) [...] was mounted with the command "mount -o async,noatime,rw /dev/da0s2 /ext" but I can't tell if async is on or just ignored, no error message. And I still have to run svnlite cleanup /ext/ports until svnlite stops bailing out. When newfs was written, I passed -t to it to enable trim, which seems to make a difference on this for deletes but not writes. Can anyone please suggest anything I can so to speed up disk i/o? And is async being applied or ignored? thanks, -- John tech-li...@zyxst.net _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
