blkid hängt manchmal (aufgewärmt)
Hallo Liste,
vor schon längerer Zeit hab ich mal einen Thread losgetreten zu dem Thema, und
heute ist genau das wieder aufgetreten.
Peter Funk gab mir damals den Rat, das ganze mit strace mal nachzuverfolgen.
was ich heute getan habe.
Leider kann ich das Ganze nicht dahingehend interpretieren, dass ich der
Ursache auf den Grund käme.
hier die Ausgabe von strace blkid:

Das device /dev/sdg1 entspricht einer USB-Platte, die vorhin noch dran hing,
die ich aber inzwischen entfernt habe.
Gibt die Ausgabe hinweise, was hier manchmal schief läuft? blkid hängt nicht
immer.
Danke im Voraus
