Ich habe ZFS (0.6.5) in meinem Centos 7 installiert und auch einen Zpool erstellt. Abgesehen von der Tatsache, dass meine Datensätze beim Neustart verschwinden, funktioniert alles einwandfrei.
Ich habe versucht, dieses Problem mithilfe verschiedener Online-Ressourcen und Blogs zu beheben, konnte jedoch nicht das gewünschte Ergebnis erzielen.
Nach dem Neustart , wenn ich die Ausgabe von zfs list
Befehl erhalte ich „keine Datensätze verfügbar“ und zpool list
gebe „keine Pools zur Verfügung“
Nach einer Vielzahl von Online - Forschung zu tun, konnte ich es manuell durch den Import der Cache - Datei funktioniert zpool import -c cachefile , aber Trotzdem musste ich zpool set cachefile = / etc / zfs / zpool.cache Pool vor dem Neustart ausführen , um es später nach dem Neustart zu importieren.
Das ist wassystemctl status zfs-import-cache
sieht aus wie,
zfs-import-cache.service - Import ZFS pools by cache file

#
# This is a space separated list, and will be mounted in the order specified,
# so if one filesystem depends on a previous mountpoint, make sure to put
# them in the right order.
#
# It is not necessary to add filesystems below the root fs here. It is
# taken care of by the initrd script automatically. These are only for
# additional filesystems needed. Such as /opt, /usr/local which is not
# located under the root fs.

Ich bin nicht sicher, ob dies ein bekanntes Problem ist. Wenn ja, gibt es eine Problemumgehung dafür? Vielleicht eine einfache Möglichkeit, meine Datensätze nach dem Neustart und vorzugsweise ohne den Overhead einer Cache-Datei zu erhalten.
