Description Avi Tal 2011-01-19 08:46:50 UTC 
Description of problem:
rhevm: IC79
vdsm22-4.5-63.10.zCream
vdsm22-cli-4.5-63.10.zCream
vdsm22-reg-4.5-63.10.zCream
vdsm22-faqemu-4.5-63.10.zCream

As part of testing 29 SD's (one LUN per SD) I've tested an attachment of around 5 SD's in a row (after having 15 SD's already running) which leads to many  resource timeout and load of vgs/pvs commands.

[root@navy-vds3 t]# grep /sbin/pvs /var/log/vdsm/vdsm.log |wc -l
272
[root@navy-vds3 t]# grep /sbin/vgs /var/log/vdsm/vdsm.log |wc -l
512


Steps to Reproduce:
1. attach multiple (after having around 10 already activated) SD's in a row 
2.
3.
