NASLite Network Attached Storage

Can any one help me on this one ? it's doing my head in

i have two drives which are set to mirror at 01 hours using the following
/Disk-2/01

Both drives are are WD Caviar Green 1.0 TB 32MB Cache SATA II

after swapping the contents from my old drive to new ones i have run into mirror errors.

to swap contents i installed one drive then set to mirror, then the next day replaced the second drive.

after both drives were installed and running , the mirror process is failing with the following message.

sent 14767157399 bytes received 7282 bytes 32277955.59 bytes/sec

Mirror Details Log: MIRROR LOG

the mirrorlog.txt file says that a file has failed to verify

i have tried to replace this file on my usable drive with a backup copy from a cd and it is still failing to mirror ( twice now)

The file that fails to mirror mirrored ok on the previous drives

you had 2 drives and one was mirroring the other. Then you replaced one of the drives and set it to mirror. Which drive did you replace and what is it mirroring?

I've done this before and it's not that hard to do. Assume we have disk 0 and 1 and that 1 is set to mirror 0. Start when the mirror is current and the files on 0 and 1 are in sync. Then, using the admin disable the mirror on drive 1. Replace disk 0 with a new one, format mount and set it to mirror the old mirror drive which should still be 1. Set the mirror to happen on the turn of the hour by checking the server time. that way you don't have to wait a whole lot. After the mirror does it's thing, you'll have a new drive 0 with the original content. Disable the mirror on it, check the files to see if everything is ok and then replace the old disk 1 with the new one, format, mount and set it to mirror 0. It's a piece of cake.

the thing to remember here is you set a drive to mirror a source and not the other way around.

That is how i did the upgrade, although left it to mirror over night as the old drive which was nearly full was 500 Gig.

The second drive is mirroring partley then aborting, when i look at mirrorlog.txt it is the same file that is failing to mirror,

files are mostley cad, gerber files and plots

as said above all the files on drives mirrored fine for several months prior to this.
the file that fails to mirror has been replaced with a copy that i have on a cd with the same result, drive tests and file test come back ok.

the mirrorlog.txt file says that a file has failed to verify

so has the file been mirrored then failed to verify, or has the file that requires to be mirrored failed a checksum test (if naslite does this i dont know) ???


steve

that could happen if the drive has a bad spot on it where that file is. do a fs check and repair with bad blocks. i bet you'll show some bad blocks on the source drive.

by fs check you mean the file structure tests option 6 in drive config ?

steve

that's the one, takes some time but does the job.
