After downgraded to 'lvm2-2.02.56-8.el5_5.6', the problematic host commands return much faster: time pvs: real 0m1.098s user 0m0.060s sys 0m0.120s Fixed in lvm2-2.02.74-6.el5.

LVM: Run-Time Regression for LVM commands in RHEL5.6. Two hosts working in the same environment, against same storage machine, but with different lvm version. the host with the newer LVM version (lvm2-2.02.74-5.el5) provide slower Run-time results for lvm commands ('pvs'. - Attached log file 'pvs -vvvv' output. 'time pvs' using - lvm2-2.02.56-8.el5_5.6: ****************************************** real 0m1.137s user 0m0.050s sys 0m0.168s 'time pvs' using - lvm2-2.02.74-5.el5: *************************************** real 0m9.409s user 0m0.442s sys 0m1.175s Note: ******* - hosts connected to 56 devices on NEXENTA storage (multipath -ll | grep NEXENTA| wc -l = 56) . - This issue causes hosts with lvm2-2.02.74-5.el5 to fail on timeout on VDSM 'connectStoragePool' (RHEVM)
