Re: [Nfs-ganesha-devel] Readdir with nfs4err_serverfault

Hi Daniel, Like you said, only if junction is a directory, callback getattrs is called. Which means that file type is directory. In mdcache_getattrs(), call to mdcache_refattrs() returns NO_FILE_TYPE. To me it seems like in between call from nfs_export_get_root_entry() and mdcache_refattrs(),

Re: [Nfs-ganesha-devel] Readdir with nfs4err_serverfault

I don't think it's the check for type==DIRECTORY. If that fails, you'll get the error message "Failed to get root for..." which is not in the log snippet. The callback is only called if the getattrs() on the junction obj succeeds, so maybe it's failing? A reproducer would help a lot, if

Re: [Nfs-ganesha-devel] Readdir with nfs4err_serverfault

Thanks for reply. I investigated further and looking at log it seems that error occurs only at Junction point somehow. nfs4_readdir_callback :EXPORT :DEBUG :Need to cross junction to Export_Id 1 Path / nfs4_readdir_callback :RW LOCK :F_DBG :Unlocked 0x1f8ec08 (>state_hdl->state_lock) at

Re: [Nfs-ganesha-devel] Readdir with nfs4err_serverfault

That's much better. A few fixes have gone in since 2.4.1 relating to readdir, mostly relating to large directories, or concurrent access from multiple clients, or readdir in the presence of add/delete/rename that turned up during stress testing for RHGS. It might be worth it to attempt to

Re: [Nfs-ganesha-devel] Readdir with nfs4err_serverfault

Okay, that's a very old tag, and lots of changes have gone in since. We won't be able to easily nail down what changed, but -dev27 isn't necessarily expected to work properly. Daniel On 02/28/2017 01:06 PM, Supriti Singh wrote: > This package was created from the tag 2.4-dev-27. > > > >

Which exact version of 2.4 are they using? If it's 2.4.0.3 or earlier, then attribute access was reworked in 2.4.0.4 to fix a lot of races. Daniel On 02/28/2017 12:18 PM, Supriti Singh wrote: > Hello All, > > For one of our client, using nfs-ganesha v2.4 and ceph v10.2.4, readdir > fails with
