I/O failure on shared drive during failover

[gqma0]

Hi everyone.

I just setup an MSCS following the step by step URL () from Microsoft.

I setup a File share resource in order to test the I/O access to the shared drive during a failover and the test is failing everytime I read or write data between the failover. The error is as followed

Can not copy "filename". An unexpected Network error occured

The shared drive is still accessible through the network after the failover to the other node but the read/write always fails.
I increased the "looks alive" and "is alive" poll interval to 60s. but it doesn't make any difference.

What am I doing wrong ?

Thanks in advance
Cheers

Hi,
I don't know if I have understood.

1) You have to create a share using MSCS (create application?) and not using normal way to create share
in Windows.

2) If you don't follow this way, after failover, disk (F?)
is not available at node A.

3) During failover, also well created shares, give error
accessing them.

Have I understood something of your problem ?

bye

Hello Victorv.

First of all, thank you for replying.

1) Indeed the share has been created via a new resource within the group and not by using the normal way via file explorer.

2) During failover, the F: drive is accessible on second node and available on the network

The problem is simply that the access to the share drive through the network is unavailable for a short period (few sec.) and any I/O on the share will result in a failure.

We have applications we need to certify against MSCS and I need to make this work for a demo


Once again, Thanks a mil. Much appreciated
Gaetan

Victorv,

I found my answer in the MSCS general FAQ

MSCS failover time: If MSCS recovers from a server or application failure, or if it is used to move applications from one server to another, the application(s) will be unavailable for a non-zero period of time (typically under a minute.)

Thanks anyway
