I have a FreeBSD/Apache web server which has been running fine for almost 50 days since the last reboot. I just ran fsck -n out of curiousity, and got in part the following: ** /dev/rda0s1e (NO WRITE) ** Last Mounted on /usr ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference Counts ** Phase 5 - Check Cyl groups BLK(S) MISSING IN BIT MAPS SALVAGE? no SUMMARY INFORMATION BAD SALVAGE? no CLEAN FLAG NOT SET IN SUPERBLOCK FIX? no 11830 files, 915788 used, 574323 free (12715 frags, 70201 blocks, 0.9% fragmentation) Apart from a few a few user tasks having crashed or been killed, I'm not aware of any problems on this machine. So my first question is, how does filesystem damage (I assume the above problems are minor and repairable) occur in this situation? Shouldn't the kernel isolate the filesystem integrity from application problems? Secondly, can these problems be repaired without taking the server down? Is it worth repairing them? (At least if the system were clean, it would be clear if further problems occurred.) -- Graeme Tait - Echidna To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
