Red Hat Bugzilla – Bug 237406
Copying files via NFS mount pauses indefinitely
Last modified: 2007-11-30 17:12:02 EST
Description of problem: When copying many SMALL files from a mounted NFS file
system, the copy process will copy some files, then pause indefinitely, then
copy some more, then pause again.
Version-Release number of selected component (if applicable):
all the time. DOES NOT HAPPEN WITH ORIGINAL 2.6.18-1.2798.fc6 KERNEL
Steps to Reproduce:
1. mount nfs file system
2. copy a directory with hundreds of small files
3. Reverting to old kernel, no problems appear.
The pauses are VERY long, so much so that NFS is unusable for copying a large
directory full of small files. Copying one large file however does not cause any
problem. It seems to be related to the number of files, not the size.
Further investigation reveals that this behaviour is dependant on the type of
ethernet NIC. Changing to another card type (e100) clears the problem. The
faulty behaviour occurs with the "forcedeth" driver for nVidia NIC nForce 2
ethernet controller. Should I file another bug?
If the problem continues to exist, Yes.
