[MacTUG] Permissions/Very Disk Issues

[Steve Hellyer]

Jeff you said on one of the disks. Yet Verify would be a volume level  
check on filing system. Two drives make up the mirrored volume unless  
it says that one of the drives are degraded.  Which means you want to  
pull that degraded drive out and either replace or place it back in to  
see it the mirror rebuilds first.  Once rebuild then run Verify  
volume.  If it doesn't rebuild the mirror then that disk is bad and  
needs to be replaced.  If rebuilding mirror works then try verifying  
volume.

Keep in mind you can't have the server in action while you verifying  
disk because someone remotely maybe changing files over network. You  
will get errors if you verify and server is live with users making  
changes.

If after this you still can't repair then disk then I like DiskWarrior  
for making repairs. But TechTools is also fairly good.

Question... Do you have a UPS on this server with a USB signal cable  
to server?
