Bug#696765: linux-image-3.2.0-4-686-pae: System freezes under high I/O load (swap issues)
Package: src:linux
Version: 3.2.35-2
Severity: important
Dear Maintainer,
A little backgroud. My system is installed on IBM ThinkCentre T52 machine with 512MB RAM.
There is one HDD with following partition schema:
--------------------------------------------------
copam:~# fdisk -l /dev/sda
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0xad28b869
Device Boot Start End Blocks Id System
/dev/sda1 * 63 20000924 10000431 83 Linux
Partition 1 does not start on physical sector boundary.
/dev/sda2 20000925 1953525167 966762121+ 5 Extended
Partition 2 does not start on physical sector boundary.
/dev/sda5 20000988 21992984 995998+ 82 Linux swap / Solaris
Partition 5 does not start on physical sector boundary.
/dev/sda6 21993048 1953525167 965766060 83 Linux
--------------------------------------------------
(I know about partition alignment - it's a temporary disk which will be replaced with new one.
I will repartition it correctly.)
Few weeks ago I decided to start making system backups on a 4GB pendrive. It's formatted with
ext4 with following partition schema:
--------------------------------------------------
copam:~# fdisk -l /dev/sdb
Disk /dev/sdb: 4003 MB, 4003037184 bytes
63 heads, 48 sectors/track, 2585 cylinders, total 7818432 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000c83a1
Device Boot Start End Blocks Id System
/dev/sdb1 131072 7818431 3843680 83 Linux
--------------------------------------------------
I'm using following rsync command to make the backups:
rsync -aAXv --delete /* /mnt/backup --exclude={/boot/swap,/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/lost+found,/home/*}
Unfortunately few days ago my system started to experience strange freezes during execution of rsync.
In most cases system just freezes and only hard reset can help. There are no system dumps in log files.
Sometimes I could see following errors in the console:
task jbd2/sdb1:xxx blocked for more than 120 seconds.
After some analyzing I found that probably issue is related to my swap configuration. Until reconfiguration
I used following swap setup:
--------------------------------------------------
copam:~# cat /etc/crypttab
#<name> <device> <password> <options>
swap /dev/sda5 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256
copam:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
LABEL=sys-debian / ext4 defaults,noatime,errors=remount-ro 0 1
LABEL=data /home ext4 defaults,noatime,errors=remount-ro 0 0
/dev/mapper/swap none swap sw 0 0
--------------------------------------------------
Some time ago I decided to replace swap partition with file. I've created 512MB /boot/swap file
and reconfigured swap settings to this:
--------------------------------------------------
copam:~# cat /etc/crypttab
#<name> <device> <password> <options>
fswap /boot/swap /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256
copam:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/mapper/fswap none swap sw 0 0
--------------------------------------------------
Since then my system freezes every time I run rsync job. The following table describes when system freezes:
+----------------------------+----------------+
| Swap type | Bug triggered? |
+----------------------------+----------------+
| No swap (swapoff -a) | NO |
| Swap mounted in /dev/sda5 | NO |
| Swap mounted in /boot/swap | YES |
+----------------------------+----------------+
Here are some memotry and I/O details in the moment when system went to freeze state. Those are different
every time. According to numbers there are no issues with swap usage (if I understand correctly):
