Here is a new session where I'll capture everything - well, on the defrag I'll do a snip. #btrfs fi defrag -v -r /home/ ...there follows a list of files that just scrolls infinitely.... /home/ermesa/.dropbox-dist/dropbox-lnx.x86_64-74.4.115/_bisect.cpython-37m- x86_64-linux-gnu.so /home/ermesa/.dropbox-dist/dropbox-lnx.x86_64-74.4.115/ tornado.speedups.cpython-37m-x86_64-linux-gnu.so /home/ermesa/.bash_history total 1 failures # sync # btrfs sub snap -r /home/ /home/.snapshots/2019-06-10-2353 Create a readonly snapshot of '/home/' in '/home/.snapshots/2019-06-10-2353' # btrfs send -vvv -p /home/.snapshots/2019-06-10-1718/ /home/.snapshots/ 2019-06-10-2353/ | ssh root@tanukimario btrfs receive /media/backups/backups1/ supermario-home At subvol /home/.snapshots/2019-06-10-2353/ ERROR: link ermesa/.mozilla/firefox/n35gu0fb.default/bookmarkbackups/ bookmarks-2019-06-10_679_I1bs5PtgsPwtyXvcvcRdSg==.jsonlz4 -> ermesa/.mozilla/ firefox/n35gu0fb.default/bookmarkbackups/ bookmarks-2019-06-09_679_I1bs5PtgsPwtyXvcvcRdSg==.jsonlz4 failed: No such file or directory Same error as before. So I go to tanukimario and del the errored subvol. Let me try with -vvv on the receive as well. Well, that produces a ridiculous scrolling list that I can't possible capture. Perhaps just -v? No, that's the same. So then I tried this command: # btrfs send -vvv -p /home/.snapshots/2019-06-10-1718/ /home/.snapshots/ 2019-06-10-2353/ | ssh root@tanukimario btrfs receive -vvv /media/backups/ backups1/supermario-home > receive.log But my bash-fu was bad and it didn't put anything into the log other than "At snapshot..." So yeah.... What scrolled on my screen ended like this: write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ 32C1CAC72D7CACC3630A470C6622283DA500617A - offset=540672 length=49152 write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ 32C1CAC72D7CACC3630A470C6622283DA500617A - offset=589824 length=49152 write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ 32C1CAC72D7CACC3630A470C6622283DA500617A - offset=638976 length=49152 write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ 32C1CAC72D7CACC3630A470C6622283DA500617A - offset=688128 length=34158 utimes ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ 32C1CAC72D7CACC3630A470C6622283DA500617A write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ DC0F9B96CE8C66CE51826341395D9B8805053D05 - offset=0 length=49152 write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ DC0F9B96CE8C66CE51826341395D9B8805053D05 - offset=49152 length=49152 write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ DC0F9B96CE8C66CE51826341395D9B8805053D05 - offset=98304 length=49152 write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ DC0F9B96CE8C66CE51826341395D9B8805053D05 - offset=147456 length=49152 write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ DC0F9B96CE8C66CE51826341395D9B8805053D05 - offset=196608 length=11390 utimes ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ DC0F9B96CE8C66CE51826341395D9B8805053D05 unlink ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ FEFC32BF08374B9F91B5B002FF51DF3DFB21B667 utimes ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ 177BF2896EEBDB17A538A6ACB13C62925D0E84CA - offset=0 length=12280 utimes ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ 177BF2896EEBDB17A538A6ACB13C62925D0E84CA write ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ A0BC2B69D3EACA6005AFF72A4EC168ECC4DFC764 - offset=0 length=220 utimes ermesa/.cache/mozilla/firefox/n35gu0fb.default/cache2/entries/ A0BC2B69D3EACA6005AFF72A4EC168ECC4DFC764 unlink ermesa/.cache/ksycoca5_en_cJ+y22ar1ZzIcHsefGXiujDwk34= unlink ermesa/.cache/ksycoca5 utimes ermesa/.cache utimes ermesa/.cache link ermesa/.mozilla/firefox/n35gu0fb.default/bookmarkbackups/ bookmarks-2019-06-10_679_I1bs5PtgsPwtyXvcvcRdSg==.jsonlz4 -> ermesa/.mozilla/ firefox/n35gu0fb.default/bookmarkbackups/ bookmarks-2019-06-09_679_I1bs5PtgsPwtyXvcvcRdSg==.jsonlz4 ERROR: link ermesa/.mozilla/firefox/n35gu0fb.default/bookmarkbackups/ bookmarks-2019-06-10_679_I1bs5PtgsPwtyXvcvcRdSg==.jsonlz4 -> ermesa/.mozilla/ firefox/n35gu0fb.default/bookmarkbackups/ bookmarks-2019-06-09_679_I1bs5PtgsPwtyXvcvcRdSg==.jsonlz4 failed: No such file or directory -- Eric Mesa
