Thanks for your suggestions Adam. I did more testing using btape. Even with a brand new tape the "label" command worked but "readlabel" immediately afterwards failed with a BB02 error. I also noticed tapes labelled with Bacula 7.4.5 would "readlabel" fine, but those labelled using 9.2.2 would fail "readlabel". After using btape to write EOF markers to a new tape it caused subsequent btape commands to reject the tape as read-only. Next I tried a package update (Arch Linux pacman -Syu) and reboot. This resolved all issues! This server is kept up-to-date, so the only change of significance was a new kernel version (4.19.12). To be able to utilise the problematic tapes labelled by Bacula 9.2.2 I used btape "rewind", made a 100 MB file (using yes) and cat > /dev/nst0. This allowed btape "test" to succeed. Next I used bconsole to "purge" then "relabel" to a temporary name then another "purge" and final "relabel" to reflect the barcode name. The result is Bacula 9.4.1 rewrote the tape labels and properly report the volbytes in "list volumes" (I initially used "delete", "label" and "add", but the volbytes report as zero). Anyhow thanks again for your suggestions. It's great to have Bacula working again. _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
