Upgrading from 2.2.20, I'm seeing vastly increased network traffic,
and after poking around a bit, I find that all calls to open() on
files on NFS-mounted partitions generates one UDP packet. Switching
on NFS debugging, and then saying
$ cat file
$ cat file
shows me this:
Jan 13 16:27:23 litos kernel: NFS: refresh_inode(b/876609548 ct=1 info=0x2)
Jan 13 16:27:23 litos kernel: nfs: read(//file, 4096@0)
Jan 13 16:27:23 litos kernel: nfs: read(//file, 4096@17)
Jan 13 16:27:23 litos kernel: nfs: flush(b/876609548)
Jan 13 16:27:23 litos kernel: NFS: dentry_delete(//file, 0)
Jan 13 16:27:24 litos kernel: NFS: refresh_inode(b/876609548 ct=1 info=0x2)
Jan 13 16:27:24 litos kernel: nfs: read(//file, 4096@0)
Jan 13 16:27:24 litos kernel: nfs: read(//file, 4096@17)
Jan 13 16:27:24 litos kernel: nfs: flush(b/876609548)
Jan 13 16:27:24 litos kernel: NFS: dentry_delete(//file, 0)
The partition is mounted with just
$ mount server:/db /db
Adding a "-o actimeo=100" makes no difference.
Is this supposed 1) to be this way, or 2) a bug, or 3) a
misconfiguration on my part?
