hi i thought i would also share my experience
i have a mailserver in my office which has around 300 local users. i installed a backup server for this server in a new PC. i installed gentoo linux on the mirrored disks and did some stress tests and it was just fine. because i am a total noob in scripting, i installed webmin and tried to add these 300 users by a batch file. it created the first 10 odd users and then gave error, saying no such file or directory. webmin failed to create the home directories. it said I/O error, i checked in the console for any disk read/writes it said I/O error. i unmounted the partition and did a reiserfsck and it showed only one error and it fixed it. thereafter it worked fine. but the same problem can be reproduced by trying to add 10+ users from webmin. i did search google for this and found nothing relevant. i ran iozone with default options in this server for hours altogether and it completes that successfully. i did a smart test for each disk and nothing came up in that also. both disk s in the mirror are of the same make and model. i have now given up on this, i am getting a new proliant ml-150 with h/w raid for this server. regards bobby
