Anna Schumaker ea96d1ecbe nfs: Fetch MOUNTED_ON_FILEID when updating an inode ... 2ef47eb1 (NFS: Fix use of nfs_attr_use_mounted_on_fileid()) was a good start to fixing a circular directory structure warning for NFS v4 "junctioned" mountpoints. Unfortunately, further testing continued to generate this error. My server is configured like this: anna@nfsd ~ % df Filesystem Size Used Avail Use% Mounted on /dev/vda1 9.1G 2.0G 6.5G 24% / /dev/vdc1 1014M 33M 982M 4% /exports /dev/vdc2 1014M 33M 982M 4% /exports/vol1 /dev/vdc3 1014M 33M 982M 4% /exports/vol1/vol2 anna@nfsd ~ % cat /etc/exports /exports/ *(rw,async,no_subtree_check,no_root_squash) /exports/vol1/ *(rw,async,no_subtree_check,no_root_squash) /exports/vol1/vol2 *(rw,async,no_subtree_check,no_root_squash) I've been running chown across the entire mountpoint twice in a row to hit this problem. The first run succeeds, but the second one fails with the circular directory warning along with: anna@client ~ % dmesg [Apr 3 14:28] NFS: server 192.168.100.204 error: fileid changed fsid 0:39: expected fileid 0x100080, got 0x80 WHere 0x80 is the mountpoint's fileid and 0x100080 is the mounted-on fileid. This patch fixes the issue by requesting an updated mounted-on fileid from the server during nfs_update_inode(), and then checking that the fileid stored in the nfs_inode matches either the fileid or mounted-on fileid returned by the server.
