rear-gw2.log

mailinglists35 commented at 2018-10-15 18:32:

grepping the log I see 'type ldd' to obtain ldd path. this is wrong. it should do a readlink -f $(type -p ldd) to find the real path to ldd

mailinglists35 commented at 2018-10-15 19:09:

it DOES work if instead I copy REQUIRED_PROGS from /usr/share/rear/conf/default.conf to local.conf and add my binaries there

Your

PROGS=(
zfs
zpool
zdb
zstreamdump
mount.zfs
)

is wrong (or more precisely ReaR does exactly what you specified this way).
Read the initial comments in usr/share/rear/conf/default.conf
https://raw.githubusercontent.com/rear/rear/master/usr/share/rear/conf/default.conf
how to correctly add items to an existing bash array.

FYI:
Regarding default PROGS versus default REQUIRED_PROGS
see the related https://github.com/rear/rear/issues/892

I tried also with PROGS=( 'zfs' 'zpool' ) and get the same result

gdha commented at 2018-10-16 09:28:

@mailinglists35 if you add binaries to PROG or REQUIRED_PROGS always make sure that the previous content of the array is not lost, e.g.
PROGS=( "${PROGS[@]}" zfs zpool )
