Hello folks, I just spotted a very strange bug on 11.1-RELEASE. (It might be fixed already?) While working with my ZFS (mirrored pool / 2 SSDs), I wanted to=20 originally track 11-STABLE and moved my original /usr/src around. The original steps were: 1) zfs snapshot lazarus/usr/src@RELENG_11.1 2) zfs clone lazarus/usr/src@RELENG_11.1 lazarus/usr/src-RELENG_11.1 3) zfs promote lazarus/usr/src-RELENG_11.1 4) zfs destroy lazarus/usr/src ... So nothing too fancy (lazarus is the name of my pool). I didnt first notice, but after doing this I get now intermixed output=20 while using mount(8) and df(1). EXCERPT ----------------------------------------------------------------------- lazarus/usr/src-RELENG_11.1@RELENG_11.1/dev/ada3p3 on=20 /virtuals/therion/images (ufs, local, journaled soft-updates) lazarus/usr/src-RELENG_11.1@RELENG_11.1/dev/zvol/lazarus/home/therion.eli= =20 on /home/therion (ufs, local, journaled soft-updates) lazarus/usr/src-RELENG_11.1@RELENG_11.1/dev/fuse on /home/therion/.gvfs=20 (fusefs, local, nosuid, synchronous, mounted by therion) ----------------------------------------------------------------------- So what is happening here is that the=20 "lazarus/usr/src-RELENG_11.1@RELENG_11.1" is prepended to the original=20 lines, which would normally *not* include this. This doesnt happen with all lines.... only these ones - after the last=20 line it continues with: 192.168.0.5:/warehouse on /warehouse (nfs, nosuid, nfsv4acls, mounted by=20 therion) lazarus/usr/src on /usr/src (zfs, local, nfsv4acls) so just normally... The RELENG_11.1 dataset I've created is not mounted: EXCERPT ----------------------------------------------------------------------- root@lazarus:~ # zfs get mounted lazarus/usr/src-RELENG_11.1 NAME PROPERTY VALUE SOURCE lazarus/usr/src-RELENG_11.1 mounted no - ----------------------------------------------------------------------- Has anyone ever spotted this? I suspect a parsing error while consuming the information mount(8)=20 needs, wherever this information comes from. regards, Georg --=20 Georg Bege Mail: georg@bege.email XMPP: therion@ninth-art.de IRC: megaTherion @ Freenode
