* shell: remove the directories emptied by volume.fsck's filer entry purge volume.fsck -findMissingChunksInFiler -reallyDeleteFilerEntries deleted the orphan entries but left their parent directories behind, so a namespace accumulated empty directories that had to be cleaned up by hand. Remember the parent of every purged entry and, once the purge is done, walk up from each one deleting the directories that are now empty. The delete is non-recursive, so the filer itself rejects a directory that still has children; a bucket and a directory that is an S3 object of its own are left alone. Claude-Session: https://claude.ai/code/session_01BncsNo2RVANCDtdbw96Kfc * shell: keep a directory volume.fsck saw change under it The empty-directory sweep read the entry to spot an S3 directory key object and then deleted unconditionally, so a directory promoted to an object in between was removed anyway. Delete with the mtime the lookup returned, leaving the filer to skip a directory that has changed since. Claude-Session: https://claude.ai/code/session_01BncsNo2RVANCDtdbw96Kfc * shell: leave a directory volume.fsck just saw written for the next run The mtime the delete is conditioned on has second resolution, so a write landing in the same second as the one already on the directory is indistinguishable from it and the directory would still be deleted. Skip a directory modified within the last few seconds. A write after the lookup then always carries a later second than the one the delete carries, and the sweep picks the directory up on the next run. Claude-Session: https://claude.ai/code/session_01BncsNo2RVANCDtdbw96Kfc * shell: skip a directory volume.fsck cannot condition a delete on A zero mtime disables the delete's condition at the filer, so a directory whose entry carries none was removed unconditionally and a concurrent promotion to an S3 object went with it. Leave such a directory alone. Claude-Session: https://claude.ai/code/session_01BncsNo2RVANCDtdbw96Kfc * shell: hold volume.fsck's quiet period to the cutoff second itself Mtime keeps whole seconds, so a directory whose mtime lands on the cutoff second was written up to a second after it. Skip that directory too, so the quiet period fails closed. Claude-Session: https://claude.ai/code/session_01BncsNo2RVANCDtdbw96Kfc
