| |
I have tryed to setup the most reliable disk server I could.
The selected configuration is: - 350 Mhz pentium II based PC from Dell - 2.0.36 stock kernel - / and swap mounted on the EIDE internal disk - Buslogic BT958 SCSI controler - 4 x 45 Gb disks - 2 x 8 Gb disks - 3C905 ethernet card - UPS the disks are linked to the controler with short and high quality cables.
I selected maximum performances on the SCSI controler Bios which means fast wild 40 Mb/s.
The system is quite loaded, and has worked for more than a month without failure (OS/2 advanced server was down roughly once a week).
This morning, the system was locked. By lock, I mean that some disks where locked ('ls' or 'umount' would never return) On the other hand, the rest of the system was working fine: I could remotely log on the machine using vnc, get a new shell, run the 'reboot' command which did not work, probably because it got locked trying to umoung some disk.
If this happends once more, is there anything I should type berore rebooting the server that could help track the bug in the SCSI driver or SCSI kernel subsystem ?
I thought the buslogic driver was the most reliable one for Linux. Would there be an even more reliable one ?
