APAR status
Closed as program error.
Error description
As of Spectrum Scale 4.2.1 on Linux, GPFS no longer creates the /dev/<fs_name> device for a filesystem. Applications that relied on the file system device under /dev to be present, or that relied on "/dev" to be displayed in the output of the mount command, must find other ways to obtain the information. As a substitute, consider the information provided by the /etc/fstab file and /proc/mounts entries. Source: http://www.ibm.com/support/knowledgecenter/STXKQY_4.2.1/c om.ibm. spectrum.scale.v4r21.doc/bl1xx_soc.htm <http://www.ibm.com/support/knowl edgecenter/STXKQY_4.2.1/com.ibm.spectrum.scale.v4r21.doc/ bl1xx_soc.htm> As a side effect; the current work directory($PWD) where running the command mmmount or mount, if there is a file or directory has the same name with the GPFS file system name($FSNAME), then the mounted file system name in /proc/mounts or /etc/mtab would become ${PWD}/$FSNAME. Spectrum scale cannot entirely control mounted file system name in this situation, as this is controlled by the Linux /bin/mount command code. This APAR is to address the explicit mmmount command via current working directory to ensure that no prefix added in /etc/mtab and /proc/mounts. However, the OS mount command and automount cases will still be subject to this Linux mount command design.
Local fix
Ensure your $PWD does not have any file/directory with the same name as the file system when running a mount.
Problem summary
GPFS removes /dev/ prefix in the device name in fstab. Now, the system mount command looks at the CWD for any same name. If exists,the full path of the CWD appends to the device name in /etc/mtab and /proc/mounts entries.
Problem conclusion
Before invoke the OS mount command on Linux, cd to an empty dir. Change back to the previous dir after mount. This will not solve file systems that don't mount via mmmount command. This includes automount file systems.
Temporary fix
