btrfs 3.14-2-amd64 btrfs_file_aio_write problem?
Hallo,
Ich benutze hier Debian Jessie mit klassischem Raid 1 (mdadm), zwei ssd disks
(Crucial_CT256MX100SSD1) und btrfs.
3.14-2-amd64 #1 SMP Debian 3.14.13-2 (2014-07-24) x86_64 GNU/Linux
Der Server ist gut unter last. Nach zwei tagen bis einer Woche sehe ich
Meldungen in messages wie unten.
Der Server bleibt zwar weiterhin erreichbar, viele services antworten aber
nicht.
Reboot geht auch nicht. Kaltstart. ps aux - hängt einfach nach ein par Seiten
Ausgabe.
Hat jemand irgend welche Tipps zur betrieb von btrfs?
fstab Zeile ist ohne spezielle Optionen.
