Error Writing File Nt_status_path_not_covered
♦ ♦ | Report Content as Inappropriate ♦ ♦ FindFirst2 and DFS links Hi all, I'm looking into a CIFS client bug report where access to a DFS link fails with -EREMOTE error intermittently. Later accesses to the DFS link succeeds as dentry revalidation gets information about the DFS link. When the failure occurs, it appears that the Server (both Samba and Windows 2k8 server) returned -EREMOTE (NT_STATUS_PATH_NOT_COVERED) in response to the FindFirst2 call on the DFS link. Looking at the CIFS Spec, PATH_NOT_COVERED is not listed as one of the possible errors for FindFirst2. So it's not clear why the Server is sending the same. In order to handle this error, the CIFS client should find a way to figure out from the Server's FindFirst2 response that it is a DFS link. The only promising bit (in File attributes) is the "Reparse Point" which is set in the response from a Windows Server. However, the Reparse point could be something other than (symlinks or volume mountpoint etc) a DFS junction. Is there a way to clearly distinguish a DFS junction? In short: * Is there a way to identify a DFS junction from the FindFirst2 response? * Is NT_STATUS_PATH_NOT_COVERED error expected for a DFS junction in the FindFirst2 response? cFYI snip (for the curious) --------- fs/cifs/readdir.c: CIFS VFS: in cifs_readdir as Xid: 105 with uid: 0 fs/cifs/readdir.c: Full path: \\mydomain\dfsroot\dfslink start at: 2 fs/cifs/cifssmb.c: In FindFirst for \\mydomain\dfsroot\dfslink fs/cifs/transport.c: For smb_command 50 fs/cifs/transport.c: Sending smb of length 142 fs/cifs/connect.c: rfc1002 length 0x27 fs/cifs/connect.c: invalid transact2 word count Status code returned 0xc0000257 NT_STATUS_PATH_NOT_COVERED fs/cifs/netmisc.c: !!Mapping smb error code 3 to POSIX err -66 !! fs/cifs/cifssmb.c: Error in FindFirst = -66 fs/cifs/readdir.c: initiate cifs search rc -66 fs/cifs/readdir.c: CIFS VFS: leaving cifs_readdir (xid = 105) rc = -66 fs/cifs/file.c: Closedir inode = 0xd3f3acf0 fs/cifs/file.c: CIFS VFS:

And /tmp was located on its own partition, that had too few space for big MySQL requests.

Problem were inodes, I had too many small files and my inodes were full.
