Salut
am urmatoarea problema:
Contextul: 2 masini vmware esxi cu datastorage comun pe un openfiler iscsi
target.
Masinile virtuale ruleaza foarte bine, DEOCAMDATA. DAR, daca incerc sa
copiez fisiere (upload) in datastore sau dintr-un folder intr-altul in
acelasi datastore, imi apare urmatoarea eroare in dmesg si vmware-ul pierde
accesul la datastore:
iscsi_trgt: cmnd_abort(1148) 8d4e0000 1 0 40 0 0 0
iscsi_trgt: Abort Task (01) issued on tid:1 lun:0 by sid:564049469047296
(Unknown Task)
Deocamdata eroarea apare, dupa cum am spus, doar cand copiez fisere nu si
la rularea masinilor virtuale, dar mie groaza sa ma gandesc si la o astfel
de situatie.
La reboot-ul tuturor masinilor fizice(2x vmware si 1x openfiler), lucrurile
reintra in normal.
A mai intalnit cineva asa ceva?
Atasez mai jos configurile ietd.conf si iscsid.conf de pe openfiler.
Mentionez ca versiunea vmware esxi este 4.0, iar openfiler este NSA 2.3
