MOUNT_STOP SCRIPT MAY HANG IF THERE ARE MULTIPLE FS ON THE SAME VG | |

Problembeschreibung: | |
In an integrated HA environment, if there are multiple filesystems exist on the same vg on AIX systems, the TSA move request may hang. TSA move will call the mountV9x_stop.ksh script on all the mount points in parallel. In the mountV9x_stop.ksh script, umount and varyoffvg commands are issued in a loop until varyoffvg is successful. In a scenario where there are multiple fs on the same vg, one mountV9x_stop.ksh script may be calling varyoffvg while the other mountV9x_stop.ksh may be issuing lslv prior to a umount attempt. Since varyoffvg is being invoked in a loop, this will block the lslv calls. This subsequently blocks the lslv, umount code path in the rest of the mountV9x_stop.ksh scripts, so those mount points are still mounted. This in turn causes varyoffvg call to fail. This race condition is sometimes seen in an environment where there are over 4 filesystems per vg. During this scenario, any lslv or lsvg command will hang. | |
