When QIOMKFILE is running creates file correctly, but he gets error - extra file

Problem

When QIOMKFILE is run it creates file correctly with an extra file It was found that running qiomkfile without mounting with qio option, an extra file is created: Incorrect configuration: # ls -lart | grep data01 -rw-r----- 1 sybase sybase 4294967296 Jul 14 13:33 .data01 lrwxrwxrwx 1 sybase sybase 19 Jul 14 13:33 data01 -> .data01::cdev:vxfs: -rw-r--r-- 1 sybase sybase 4294967296 Jul 14 13:36 .data01::cdev:vxfs: <<<--- EXTRA! Mount Options as seen in the /etc/mnttab: /dev/vx/dsk/datavg/encrDev /encr_devices vxfs rw,suid,delaylog,largefiles,ioerror=mwdisable,dev=510afc81276788771

Cause

If VxFS is installed and Quick I/O is licensed, Quick I/O is enabled by default when a file system is mounted. In this case, “qio” was not used when mounted as seen from the “/etc/mnttab” output. /dev/vx/dsk/datavg/encrDev /encr_devices vxfs rw,suid,delaylog,largefiles,ioerror=mwdisable,dev=510afc81276788771

Solution

Alternatively, one can use the VxFS specific mount option, “-o qio”, to enable Quick I/O as shown below without having to umount and then mount filesystem. # mount -F vxfs -o remount,qio /dev/vx/dsk/DG/VOL /MNT_POINT
