APAR status
Closed as program error.
Error description
allocp called by extendlv needs moe than an hour to complete/return in case the LV to be extended has 1000000 LPs.
Local fix
None, just wait. Use the -L flag on lsvg, lslv, etc. commands to get not blocked by the LVM lock of the VG which is taken the by extendlv the whole time.
Problem summary
allocp, called by extendlv and other LVM commands, can run for a very long time on extremely large LVs. The code to read in the LP map of the LV has room for improvement in the algorithm that reads it in and stores it in a linked list.
Problem conclusion
Enhance the algorithm to read in the lvmap so that it can do so much quicker in the normal case.
Temporary fix
