lose access to FSA when recalling EV files

[yobole]

This is becoming very frustrating now we tend to lose access to FSA when recalling EV files .. FSA is on version 10.0.3 while Enterprise vault is on 10.0.4

we have enabled passthrorugh recall and relly stuck here 

The server become responsive onlt after the large file complets which could take an hr

Any ideas on how to sole this ???

Yobole,

Do you have anything new on this issue?

Thanks,

Thank you all for all your help. It looks the SMB settings  MaxThreadsPerQueue setting to 64 on all FSA has stopped the loss of shares and server being unresponsive

The other recall issue seems to have been contained by excluding the PassThrough recall folder from AV. We are now reviewing all our AV settings

Moving forward we are now looking at centralizing EV by removing EV from all file servers and having just one EV FSA server centrally. Thus have an automated process to move files to be archived from all remote sites to this One FSA server centrally. This takes EV away from all remote sites thus making other things like windows journaling needed for Netbackup deduplication to be faster and server refresh less painful  

We then end up with just one massive FSA instead of 30 which will make managing a lot easier. Looking forward to the migration project for this :) as I guess we have a lot of placeholders to recall or move as required .:)

Hi Yobole,

Did you just add the entry MaxThreadsPerQueue

or is there anything else that you need to add/change to enhance the stability of the Windows Server 2008 file server like in the following table ?

Parameter	Value	Default
NtfsDisable8dot3NameCreation	1	2
TreatHostAsStableStorage	1	0
AdditionalCriticalWorkerThreads	64	0
MaximumTunnelEntries	32	1024
MaxThreadsPerQueue	64	20
RequireSecuritySignature	0	0
MaxMpxCt (only applicable to SMB 1 clients)	32768	50

We just applied the MaxThreadsPerQueue to resolve this issue but looking at the other settings for SMB optimisation

Cool, thanks for getting back to me.

So what version of FSA agent installed on your Win 2008 File server ?

According to this article: http://www.symantec.com/business/support/index?page=content&id=TECH185593 the problem is affecting Win2008R2 and EV FSA 9.0.2

mine is Windows Server 2008 SP2 file server (non R2) with the EV FSA agent v9.0.5 CHF 5  but still the problem exist.
