[linux-cifs-client] RE: Now Memory and I/O errors to Netapp server

[Tory M blue]

Thanks the version of Netapp is:

ONTAP 6.4.3

The error we see on the Netapp is:

Wed Oct  6 12:58:43 PDT [net_e0:notice]: CIFS SetPathInfo request 101
not implemented   

^^^^ appears CIFS is asking for something that the Netapp doesn't
understand.

So far the CIFS connect to an EMC Symetrix NAS head seems to be working
well, no issues, no complaints..

Will keep folks posted

Subject: Now Memory and I/O errors to Netapp server


I know of one serious problem with cifs client and Netapp servers. 
CIFS, unlike other clients, on FindFirst/FindNext looks at the field
which indicates the last search entry in the buffer (rather than 1st
iterating through the search entries one by one).   At least some Netapp
servers that I have tried appear to set that last entry offset
incorrectly which causes the client to give up on readdir.   There is a
reasonable workaround which will be part of the pending cifs_readdir
changes mentioned on the list a few times last month.

Once that is fixed digging deeper we may find a transact2 infolevel or
two which Netapp does not support but even if that were the case should
be easy to workaround.
