#1201: 'rm' via sftp+sshfs
-----------------------------------------+----------------------------------
Reporter: bj0 | Owner: nobody
Type: defect | Status: new
Priority: major | Milestone: undecided
Component: unknown | Version: 1.8β
Keywords: hang sftp sshfs reliability | Launchpad Bug:
-----------------------------------------+----------------------------------
I was trying to figure out what part of the bonnie++ benchmark was failing
on tahoe (via sshfs), so I mounted the sshfs interface and ran:
{{{
> bonnie -d ./mnt -s 100m -n 0 -r 50m
Writing a byte at a time...done
Writing intelligently...done
Rewriting...done
Reading a byte at a time...done
Reading intelligently...done
start 'em...
^C
Can't read data from ITC pipe.
Can't read from pipe, expected 32, got -1.
}}}
It hung for a while after "start 'em", so I checked the flog and there was
no activity, so I hit Ctr-C, which gave me those 2 errors and then the
interface hung.
I had to kill -9 sshfs to get everything to free up, then I re-mounted the
sshfs interface, did a:
{{{
> ls ./mnt
Bonnie.3520
> rm ./mnt/Bonnie.3520
}}}
And it hung on the 'rm'.
I had flogtool running for the 'rm', and the output was (below).
After restarting the tahoe client process and then reconnecting via sshfs,
I was able to delete the file.
