I recently rebuild a machine with Centos 5.8 with a brand new disk.
This machine is old and has been running 5.8 for a long period with no issues so the only thing which changed recently is the new much larger disk.
However all the file operations are extremely slow since the machine was rebuilt with the new disk.



My knowledge about OS admin stuff is very limited and I will appreciate if someone can point me to where should I be looking at for finding the root cause. What commands or utilities I could use?



There is a java based back up program running on this machine which is constantly reading from the disk but the same program was running on this machine before the rebuild too and machine has been behaving fine for almost 2 years while this program ran at all times. But now the machine is not very usable and even the back up program is crawling.



This is the output of the iostat command:

    It looks like CrashPlan is running. Maybe when the machine was rebuilt, CrashPlan was set up as if this were a new machine, one on which the files had never been backed up before. Normally when you set up CrashPlan on a rebuilt system, you can choose an existing backup to use so that it won't have to copy over everything again.

  • No, that is not the case. I did the adaption as you mentioned. It is not just the crashplan, everything is extremely slow on the machine, making it unusable for any purpose.

  • OK. If you run the CrashPlan app, what does it say it's busy doing? If you pause CrashPlan and run iotop and iostat, what is running?

files io disk







share|improve this question
















I recently rebuild a machine with Centos 5.8 with a brand new disk.
This machine is old and has been running 5.8 for a long period with no issues so the only thing which changed recently is the new much larger disk.
However all the file operations are extremely slow since the machine was rebuilt with the new disk.



My knowledge about OS admin stuff is very limited and I will appreciate if someone can point me to where should I be looking at for finding the root cause. What commands or utilities I could use?



There is a java based back up program running on this machine which is constantly reading from the disk but the same program was running on this machine before the rebuild too and machine has been behaving fine for almost 2 years while this program ran at all times. But now the machine is not very usable and even the back up program is crawling.



This is the output of the iostat command:



avg-cpu: %user %nice %system %iowait %steal %idle

And here is the snippet from the iotop command:

Though I Don't know what to look for here..



UPDATE #1



Here is the output of iotop after killing crashplan.
What is this 'rsync' process ? I am not running any rsync on the machine.
Looks like 'updatedb' and 'rsynch' are using up all the IO..

    It looks like CrashPlan is running. Maybe when the machine was rebuilt, CrashPlan was set up as if this were a new machine, one on which the files had never been backed up before. Normally when you set up CrashPlan on a rebuilt system, you can choose an existing backup to use so that it won't have to copy over everything again.

  • No, that is not the case. I did the adaption as you mentioned. It is not just the crashplan, everything is extremely slow on the machine, making it unusable for any purpose.

  • OK. If you run the CrashPlan app, what does it say it's busy doing? If you pause CrashPlan and run iotop and iostat, what is running?
