changing IO Scheduler

hi sumsum,

shure, the config of /etc/fstab on host/cluster/node is:

Code: 
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext3 errors=remount-ro 0 1
/dev/pve/data /var/lib/vz ext3 defaults 0 1
UUID=5a942cfb-0e70-4ee0-b23a-7bf7a07b0d20 /boot ext3 defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0

it´s the default config after install with install cd/iso of proxmox.

regards

@sumsum, do you have any ideas or a other user?

at the moment we haven´t found a solution for this problem. :(

right, many people have this problem. but no solution :( is not so good. we hope, that proxmox find a solution. proxmox can test on our servers, but the answer of owner martin is, you must pay a ticket. ok we buy a ticket, proxmox find a solution, and all oter users have a free fix. on a problem with so many users, proxmox must help free. its bug-support. or what you mean?

Proxmox VE is open source and free to use. If you want support and help from our team, you need to pay.

If you do not pay, we do not support you directly. Its very simple and explained in our wiki:

hi tom,

sorry for the entrys, we have get a info, that´s a bug of the last openvz kernel. we must wait for a fix of openvz kernel to solve this problem, sorry for "spam" and regards.

that is just a guess so far - lets wait till someone tested with latest adaptec firmware/drivers.

there is still no test-case to reproduce this issue.

While there is no reproducible test-case, we do have a single specific VE that - when backed up via vzdump - reliably reproduces the issue on any of our cluster nodes.
At the moment we run this VE under Hyper-V to prevent it from bringing down our nodes every night (under Hyper-V the problem does not appear).

You are welcome to log in and check it out if you choose, feel free to PM/email me.
 
did you test updated adaptec driver and firmware already?

We already have the latest supported driver for our controller in the kernel:
Code: 
modinfo aacraid
filename:       /lib/modules/2.6.32-19-pve/kernel/drivers/scsi/aacraid/aacraid.ko
version:        1.2-1[29900]custom

As for firmware, one of our controllers run 18512, the other 19076 (latest is 19109).
Both nodes exhibited the issue several times.
 
google tells that using aacraid 1.2.1-30200 solved similar issues on other rhel based distros -try it.
 
hi tom,

thanks for this nice information. we do update one of our servers today and test this driver.
can you this driver impelment in next test version of proxmox, well in last it´s the old version implemented (1.2.1-29900).?

regards

E: Mittels regulärem Ausdruck »linux-headers-2.6.32-20-pve« konnte kein Paket gefunden werden.

i think, it´s only a listing problem, well proxmox have a own kernel.
