I/O problem with sustained writes

2001-03-02 Thread Collectively Unconscious
We are having a problem with writes. They start at 14 M/s for the first hour and then drop to 2.5 M/s and stay that way. Reads do not seem effected and we've noticed this on the 2.2.16, 2.2.17, 2.2.18 and now the 2.2.19pre11 kernels. These are SMP P-IIIs from 450 to 800 MHz. Redhat 6.2 Jay -

We are having a problem with writes. They start at 14 M/s for the first hour and then drop to 2.5 M/s and stay that way. Reads do not seem effected and we've noticed this on the 2.2.16, 2.2.17, 2.2.18 and now the 2.2.19pre11 kernels. These are SMP P-IIIs from 450 to 800 MHz. Redhat 6.2 Jay -
