  都幾肯定，system unstable, 由iscsi所引起.

今日，無再行iscsi,  抄咗2個幾鐘頭file，一d事都無,
對比起昨日，win 10 conncted iscsi抄野，隔10分8分鐘，
隻431p2個network service, 死下死下咁.

Sigh,  you know what, the reason of switching to iSCSI (weeks ago) was due to ... suspecting the EXT4 (under 4.3.4) was unstable (static volume crashed)!  And now you are telling us, the iSCSI is unstable .  That means, 4.3.4 is unstable in general!  What do you say? What should we do? Downgrade to 4.3.3 ... ????

Anyway, will let you know the result of iSCSI file transfer stability by tonight.

最古怪的是，係iscsi unstable,  拖冧成個NAS,
連自身個OS都瓜埋，咁先得意.

But,  我試到係咁，可能其他人又未必......

anyway,  總算試到個大  bug出嚟.

係從新setup，無enable iscsi 嘅情況下，
現開住4個fastcopy,  另加7個dos copy batch (robocopy),
有隻vhdx (4tb dynamic) 係raid 0 (2tb*2)抄緊野.

一切正常，無出過任何error.

I think iSCSI may not be able to handle your kind of stress test.  And it dies ....

My usage of iSCSI is mostly scheduled backup task, ie., one backup task per time.

到而家，無enable iscsi後，non-stop抄咗5hrs野，
再者，用晒兩個LAN port, same network, same router
(無行port trunking)
無晒昨日死network個種情況.

可能係輕量iscsi read/write,  適逢system idle,  表面正常運作.
但唔知，去到某個peak位，或用到某某％ resource.

咁就瓜咗.

利申：純粹斷估.

Tested to copy 1TB of data from 216+II to 431P2 iSCSI, no problem at all.
