Default openbsd, fsck at boot, repair files without disk

hd99

Hi,

I have here an old laptop running well obsd with dwm.
unfortunately, hdd seems to be a bit tired, when fw_udpdate cant install the wifi driver because of an i/o error.
problem the hdd is a unique connector and seems to be out of availability. No other choice to use that one.
so I was wondering to do something, as for the first one I was doing with linux previously : run a fsck at each startup to fix iflesystem errors.

how to do that? mean, fsck_ffs sd0a but just at openbsd boot, to ensure everything is correct?

then, how to fix files errors/unavailability/missing without booting on the openbsd disc? is it possible from web to repair some files damaged by repair them one by one (md5 comparison from web?)

thank you vm

hd99 run a fsck at each startup to fix iflesystem errors.

See the do_fsck() functiin in /etc/rc. Change -p to -f

You can do an mtree check and re-extract any missing/bad files from the install image. Looks like on OpenBSD the initial checksum files are not supplied and will have to be created by the user...
