SFTP server requires re-authentication during rsync #4
Comments

The real issue is that sshfs crashes with "sshfs(45716,0x100381000) malloc: *** error for object 0x10041da90: pointer being freed was not allocated" I would like to understand why it crashes. Is there any repro case for the issue? I just mounted sshfs locally with the same flags as you and copied a few large files (~100Mb each) - everything looks fine fo me. I think I saw something similar to your crash message during early stages of "simple-lock" development. But that issue has been fixed already. I wonder if you use development version of fuse4x. If so - please try the latest development build http://dl.dropbox.com/u/3842605/Fuse4X-0.10.0-beta.dmg BTW there is no reason to abandon MacFusion.app. Fuse4X (the binary package) works perfectly fine with MacFusion. |

Thanks. I wanted to make sure the underlying structure was working properly before I used I gui to mediate the mounting. I saw the tricks for linking sshfs in MacFuse. I tried the version you indicated, rebooted, and I'm still getting the issue. I don't see the error you indicated. If I am watching the process and type my password in, it reconnects and I can restart the rsync, but it invariably fails before completing. The total directory size is only 34mb, which seems pretty small. I will say that the throughput, before crashing, seems much faster than the old MacFuse. Is there anything additional I can send? |
It is in the middle of the debug log you provided. So what you are doing? Could you please provide sequence of commands you are running (no need for usernames/real server names). Are you mounting sshfs and then sync the mounted folder with a local folder? If so then you do not need to mount sshfs - rsync works perfectly fine over ssh. sshfs should not crash in any case though and it should be fixed. |

OK, I see it in the old log, but not in the logs created since updating fuse4x. I can't do rsync directly against the server in question as I don't have full secure shell access, only SFTP. Because the old MacFuse/MacFusion.app was able to work around that limitation, I had hopes I'd be able to leverage fuse4x/sshfs in the same way. You're guess is correct. I'm trying to mount the remote server, and then perform rsync activity between the remote system and a local copy. My commands: sshfs [email protected]:/directory/path ~/localmount -o auto_cache,reconnect,defer_permissions,noappledouble,auto_xattr,debug rsync -rtPv --exclude-from=/myexclude.txt ~/localcopy/ ~/remotecopy/ rsync show error: sshfs shows: Is there anything else I can send |

Could you please show me output of 'sysctl vfs.generic.fuse4x' when sshfs is running? Also could you please run sshfs in a single-thread mode (add "-s" parameter) and show me its output - I want to see what is the first failed command. After that try to run sshfs with bigger iosize (e.g. iosize=1048576) - this will reduce number of write operations to sshfs. |

Results of sysctl vfs.generic.fuse4x Running in single thread output: rdavies3@RogOMac:~>sshfs USER@server:/dir ~/mycms -s -o auto_cache,reconnect,defer_permissions,noappledouble,auto_xattr,debug |

The log is not complete - it seems it is cut in the middle. Feel free to send the log to my personal mailbox == anatol dot pomozov at gmail |
I am a recent convert from MacFuse/ MacFusion.app to Fuse4x/sshfs. I have an SFTP server which used to mount just fine with the old regime, and it worked (usually) just fine with rsync file syncing. I'm mounting with:
sshfs [email protected]:/directory/path ~/localmount -o auto_cache,reconnect,defer_permissions,noappledouble,auto_xattr,debug
The mount is fine, and I'm able to copy individual, small files without issue. With larger files, or with rsync, everything starts out fine, but then I start getting:
unique: 0, opcode: LOOKUP (1), nodeid: 4, insize: 59
LOOKUP /myuser/sql/asu_wf_app_pkg.sql
getattr /myuser/sql/asu_wf_app_pkg.sql
