wireless network woes

1 Comment

sometimes i think that knowing too much can only complicate your life. such is the case with my wireless network at home. we bought a roughly 10 year old house about a year ago and back then it was not standard practice to wire the house for ethernet. ten years from now, wiring the house for ethernet may fall out of fashion as wireless technologies improve, but in the meantime, wired networks are still by far the easiest way to get fast performance in your network.

dns-323 file system errors

6 Comments

i was having some trouble copying a file over from the NAS. i telnet’d into the NAS and tried to copy the file over and i got an input/output error. clearly something was wrong with the disk…and then i remembered that there was a power failure last night and it could very well be that the disk got corrupted when that happened. the big question that was presented to me was how do you check the disk for errors when this happens?

surely d-link has created some tool in the webUI somewhere to fix disk errors, right? nope.

so what am i supposed to do? in linux, i’d reboot and fsck the partition…but how do i do that with the NAS? it turns out that there’s a port of fsck for DNS-323 which will reboot and let you mount the main paritions for fsck’ing. fantastic!

i’m fsck’ing the RAID volume now so hopefully that will fix up all of my problems.
