This one's been bugging me for awhile now. Also an upgrade. Original install was f11 and now at f13.
One notable observation...two PVs on the same array:
# fdisk -l /dev/cciss/c0d0
Disk /dev/cciss/c0d0: 73.4 GB, 73372631040 bytes
255 heads, 32 sectors/track, 17562 cylinders
Units = cylinders of 8160 * 512 = 4177920 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00038857
Device Boot Start End Blocks Id System
/dev/cciss/c0d0p1 * 1 51 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/cciss/c0d0p2 51 5192 20975616 8e Linux LVM
Partition 2 does not end on cylinder boundary.
/dev/cciss/c0d0p3 5192 17562 50469452+ 8e Linux LVM
Partition 3 does not end on cylinder boundary.
# pvs
PV VG Fmt Attr PSize PFree
/dev/cciss/c0d0p2 vg_sys lvm2 a- 20.00g 3.50g
/dev/cciss/c0d0p3 vg_dat lvm2 a- 48.12g 16.62g
And each of those PVs has different PE size and are mapped to separate volume groups. Created attachment 521624 [details]
System information, logs
Hi,
I have an extended version of this problem. In addition to getting entries in /var/log/messages saying:
Sep 6 15:48:54 nandan lvm[1187]: Another thread is handling an event. Waiting...
... the shutdown time is now more than 5 minutes. I see the following lines during shutdown
Not stopping monitoring, this is a dangerous operation. Please use force-stop to override.
lvm2-monitor.service: Control process exited. code=exited status=1
There are still devices being monitored
Refusing to exit.
This condition has started only after I made snapshot volumes to use in virtual machines.
Details of my machine and messages are attached in nandan-system-info.txt.gz

This also happens to me on: [root@v log]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.2 (Santiago) and is accompanied by short hangs of a few seconds every few seconds. I too have 2 pvs on one array: [root@v log]# parted -l /dev/sda | less Model: HP LOGICAL VOLUME (scsi) Disk /dev/sda: 4001GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 525MB 524MB ext4 boot 2 525MB 63.4GB 62.9GB lvm 3 63.4GB 4001GB 3937GB lvm and get tons of these error messages: [root@v log]# tail messages Dec 7 15:26:25 v1 lvm[1235]: Another thread is handling an event. Waiting... Dec 7 15:26:25 v1 lvm[1235]: Another thread is handling an event. Waiting... Dec 7 15:26:35 v1 lvm[1235]: Another thread is handling an event. Waiting...

Dec 7 15:27:15 v1 lvm[1235]: Another thread is handling an event. Waiting... and like I said, the server hangs for a few seconds every few seconds. I think I'm going to have to re-install and having the raid card present a couple volumes from the RAID10 array. Petr Rockai patched this and those messages should not appear anymore, see also rhbz #771419 comment 6 (fixed in lvm2 v2.02.91).

Can you still hit these hangs? If yes, please open a new bug report for RHEL adding an strace log and/or lvm command's -vvvv log. Fixed in lvm2-2.02.91-2.fc18. |
