[9fans] The name of filesystem test tool

[9fans] The name of filesystem test tool

[YAMANASHI Takeshi]

I remember that someone mentioned about a filesystem
integrity test tool, but I don't remember the name of the tool
nor who did.  So, could someone show me pointers, please?

My grepping 9fans-archive (since 2004-Jan) and googling did not
avail much to me.  Thank you.

For kfs, use kfscmd check.  See kfscmd(8).
For the WORM file server, use the "check" command.  See fs(8).
For fossil, use the new "check" command.  See fossilcons(8).

You are probably remembering fossil's flchk, which was a failed
experiment.  You can still use flchk, but the console command
is a lot easier to use and is safe to use on a running system.
(Flchk is not, since what it decides will be out of date by the time
you actually run the commands.)

Guess I misunderstood the use of the word 'integrity' here, ignore my last 
message :-)

steve simon started a thread called 'fs tester' on the 20th of may:

i didn't follow it completely so i have no idea whether there was any
software posted.

it is fsx, and I think I put it into the v9fs tree. We used it to test 
v9fs and it was used to find problems with the open source NFS stacks 
(linux, *bsd) etc.

Sorry for not giving clear details and using the word `integrity'
confusingly.  I only remember that the guy used the tool to test
a filesystem he was developing.  I don't remember whether it was
on Plan 9 nor linux.

Geoff sent me a tool called fsx privately
(and two versions of it!, thank you :), and I think this would be it.

I will use the tool to test a suspected RAID box
attached to a linux host.

My many thanks to you all.
