PROBLEM:

Mount error 115 on some shares? (LINUX)

SOLUTION 1:

• Running debian wheezy on a virtual machine and trying to mount some shares from the win8.1 host.

//192.168.0.10/dir1 /home/user/dir1 cifs credentials=/root/.secret.pwd,uid=1000,gid=1000,file_mode=0777,dir_mode=0777,iocharset=utf8,sec=ntlm 0 0
//192.160.0.10/dir2 /home/user/dir2 cifs credentials=/root/.secret.pwd,uid=1000,gid=1000,file_mode=0777,dir_mode=0777,iocharset=utf8,sec=ntlm 0 0
//192.160.0.10/dir3 /home/user/dir3 cifs credentials=/root/.secret.pwd,uid=1000,gid=1000,file_mode=0777,dir_mode=0777,iocharset=utf8,sec=ntlm 0 0

• The first share gets mounted correctly, but not the other two.
• This is the output we get when sudo-ing a mount -a:

Code:

mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

and this is what /var/log/syslog shows:

Code:

Mar 24 12:56:12 hostname kernel: [ 1887.029043] CIFS VFS: Error connecting to socket. Aborting operation
Mar 24 12:56:12 hostname kernel: [ 1887.030013] CIFS VFS: cifs_mount failed w/return code = -115
Mar 24 12:56:22 hostname kernel: [ 1897.052130] CIFS VFS: Error connecting to socket. Aborting operation
Mar 24 12:56:22 hostname kernel: [ 1897.053885] CIFS VFS: cifs_mount failed w/return code = -115

• The same happens at boot time.

Now, we run manually :

Code:

sudo mount //192.168.0.10/dir2 /home/user/dir2 -t cifs -o credentials=/root/.secret.pwd,uid=1000,gid=1000

SOLUTION 2:

mount error(115): Operation now in progress … CIFS VFS: cifs_mount failed w/return code = -115

• Trying to mount a CIFS path in Ubuntu and getting:
• mount error(115): Operation now in progress
• Try to look this /var/log/syslog:

Feb  9 14:08:29 ldap kernel: [143452.140157] CIFS VFS: Error connecting to socket. Aborting operation
Feb  9 14:08:29 ldap kernel: [143452.140492] CIFS VFS: cifs_mount failed w/return code = -115

• Socket error, we know what this is right? IP or port. Ping for domain/IP or Telnet to test port:

ping IP
telnet IP 445

• Telnet was timing out, port closed for IP in firewall.

SOLUTION 3:

LEM mount error(115): Operation now in progress

Overview

• This article describes an error during the LEM upgrade process where you are asked to specify a network share location containing upgrade files.
• After entering the network share as \\hostname\sharename and the username and password, LEM throws this error and will fail the upgrade process:

Mount error(115): Operation now in progress

Cause

• A network name resolution failing on the smb client in LEM.

Resolution

• Check ICMP connectivity (ping) between the hosts.
• Attempt to mount a share on the same subnet as LEM.
• Attempt to use the IP address and a simple share name when mounting the share.

e.g. \\10.1.1.1\lem\ rather than \\some_host_some_place_on_the_network\this_share.name_desktop_special_unique_and_long
