Tried to boot to a live-CD to do a fsck. But the live cd failed to initialize all SATA-controllers. trying to reset multiple times with errcode:-85 ?? so I gave up after many attempts. will try fsck.mode=force on next boot (whenever that happens), tune2fs says filesystem is clean. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
