Hi Luca, the error mean: ost grant more space than there is avaiable!!! You could check in the proc filesystem of yours client checking the cur_grant_bytes to check how much grant space those clients take. On 09/08/2010 05:02 PM, Gianluca Tresoldi wrote: > Hello everyone > > I've an installati

Hi, the ptlrcp bug is a problem, but i don't find in the Peter's logs any refer to an eviction caused by the ptlrpc but instead by a timeout during the comunication between a ost and the client. But Peter could make a downgrade to 1.8.1.1 that not suffer by the problem. My action plan could be

Re: [Lustre-discuss] I/O error on clients

Hi Peter, which 10GbE Card do you have? I've solved similar problem with a Netxen Card (HP Blade Mezzanine Card) using the nx_nic proprietary driver instead of the "open source" driver. In every case the problem is that your users fill the network between client and ost !!! On 07/06/2010 08:19

Re: [Lustre-discuss] Lustre and loop devices

If you have a huge number of very small file, is really impressive how the loopback device help. But the problem is that you could access only from 1 client. The loopback device is a ext2 or ext3 filesystem and you can not mount it from more than 1 client!!! On 06/15/2010 09:53 PM, Kevin Van Ma

Re: [Lustre-discuss] Recovery Problem

Hi Stefano, your client was evicted by the OST server, now you could explain if you have any failover configuration. To understand better the failover and the timeout issue you could read the manual at paragraph 4.3.8. Ciao. On 05/19/2010 02:34 PM, Stefano Elmopi wrote: > > > Hi, > > I have a s
