CIFS 4gb problem

[Si.]

Hopefully someone can help.

I've got Freenas 8 running as a VM on my ESXi5 setup.. I'm having problems copying files larger than 4gb to it.. I can download files larger than that (Ive downloaded a 7gb file no problem) but if I copy a file to it from another machine (either a VM or Physical) it errors at approve 4gb, every time.

Any ideas?

MORE info..

If I enable FTP I can upload files no problem, only seems to be a CIFS share.. same problem from both windows and Mac clients.

I've also experienced an issue like this - only with CIFS shares, AFP and FTP are fine. Running 8.0.3 on an i3 with a RAIDz pool, and have the issue running 8.0.4 virtualised with a RAIDz pool. Both 64bit releases. Seems to copy around 4.5~ 4.6GB of the file and throws up an error.

That's strange, I copy quite large files over 4GB often and haven't had any problem. I looked at the CIFS settings and don't see anything relevent either.

How much RAM do you have allocated?

How much RAM do you have allocated?

I'll be first to admit I'm new to FreeNAS, I have 8GB of RAM in the server, sharing a 4TB array just to me. I hope that is the info you are asking for.

I looks like from the other posts above that its related to virtual installations. I'm not sure what to suggest right now. Maybe someone else will have some ideas.

That's strange, I copy quite large files over 4GB often and haven't had any problem.

Same here, no issues with large files over 10GB. I'm using the default CIFS settings.

I have the same problem between an OSX desktop and FreeNAS 8.20Beta2

Hi All

I have the same problem copying files larger than 4Gb to my FreeNAS over CIFS. The problem occurs consistently when dragging a 7Gb file from my Macbook Pro (running OSX Lion) onto my FreeNAS share. The problem does not occurr when doing the same operation from a Linux desktop (Fedora 16). The problem also does not occur when I copy the same file from my Mac to my old Synology Diskstation which is also running a CIFS share.

So, the problem for me is between OSX Lion and FreeNAS. I drag the file over to the FreeNAS share, and it transfers up to 4.29 Gb, at which point the transfer stops and I get the following error in Finder:

The Finder can’t complete the operation because some data in “filename” can’t be read or written.
(Error code -36)

I'm running FreeNAS 8.20 Beta2 with a standard CIFS set-up. It is running on a HP Proliant N40L which has 8Gb RAM. FreeNAS is installed directly on an internal USB flash drive without any virtualisation. I have 4x 2TB disks in RAID-Z2. If anyone knows how I might fix this or troubleshoot further then I'd appreciate the advice.

Thanks
Nick

Further to my previous post, I've run debugging logs on FreeNAS when repdocing the failure. Below is a couple of extracts from /var/log/samba/log.smdb. It seems that as the file transfer proceeds, there are many 'real_write_file' instructions executed to write the incoming data to the disk. Each of these seems to be followed by read_smb_length_return_keepalive, except for the final one (when the failure happens) which is instead followed by set_sec_ctx and then security_token_debug. Details are as follows:


Good (this is one of many 'writes' as the file transfer proceeds):

I hope this might shed some light on what's happening with my issue.

A better log sequence

I've captured a better log sequence (hopefully). Here we are mid-transfer (filename being copied is London.mov - "Mac Movies" is the destination folder on the FreeNAS CIFS share)…

Then a bit later, just as 4.29Gb is approaching:

Then at 4.29Gb on the dot, I get the Mac Finder error (-36) and these logs:

Any thoughts on what might be happening here?

I have just upgraded to 8.20beta3 and problem persists.

 

[dstwins]

I have the same problem..

I've this same problem from 8.0.4 - 8.2 BETA 3 and it definitely appears to be related to CIFS and OSX. I can push large (+5GB) on my windows box or through FTP/SFTP/RSYNC.. and downloading is not a problem, but when I upload via CIFS it bombs.

Initially I thought this was memory related (Had some stability problems with my 8GB RAM, so I moved to 4GB and a more stable set.. (my 8GB seems to like 2.2V) and my stability problems went away, as well as a potentially bad disk.. (still have smart errors on one 1TB SATA drive in my 20 Disk cluster).. but I have another 8 disks (separate ZFS zpool) and still the same issues.

It may be speed related.. (SFTP/FTP I peak about 30MBps, vs. CIFS I seem to peak around 48MBps (Full duplex gig network)), so perhaps we are simply over-running ZFS buffer space?

FYI.. system is a 3.33Ghz Core 2 Duo rig with 4GB (64Bit system).. I'll be back up to 8GB Soon and will replace the ailing drive and will retest, but so far, any large files from my mac, I have to use SFTP/Rsync/FTP.

Hi - thanks for taking the trouble to respond. It sounds like you have the same problem as me. My comments around your findings are as follows:

Is the problem RAM related? Well, I'm running 8Gb on a brand-new build server and the problem occurs 100% every time. I'm not having any stability issues, so I assume my RAM is good.

Speed related? Interesting theory - is ZFS becoming overloaded? Like you, I can FTP files larger than 4Gb too and from the box no problem. I can also push files through CIFS from a Fedora desktop so to me that suggests a Mac specific issue. My Mac is also connected wirelessly (802.11n) and according to the FreeNAS network throughput graph I'm getting about 80mps, which I assume is quite within limits.

The key thing for me is that the transfer fails, without exception, at 4.29Gb, according to the OSX Finder progress bar. I don't know how to troubleshoot this further though - after all, this may be an OSX issue rather than one on FreeNAS.

I just googled "afp 4.29GB" and found one other person with the same problem (not using FreeNAS), but there wasn't any solution. So it does seem like a OSX issue at the moment.

Hi thanks. Whilst I accept the root cause of this might in in Mac OSX, I still believe there is a combined issue here. The reason being that I can copy files in excess of 4Gb to my Synology Diskstation over Samba with no issues whatsover from OSX. As such, there is some interaction between OSX and FreeNAS specifically which is failing here.

The link you provided is useful in that it confirms 4.29 as precisely 4Gb, so I'll do some more searching based on that being the point of failure here.

Make sure that the filesystem is GPT and not MBR...

 

[dstwins]

My systems are all GPT.. (3TB HFS+ drives.. so no MBR).. But I never had this problem before.. so I wonder if its some interaction with latest rev/patch of Lion. I push a LOT of data through my NAS on a daily basis but 95% is from 3 OSX computers (hackintoshes and a MacBook Pro) with the remaining 5% from about 30 computers and VM's and so far, its been only from 1 hackintosh which I keep patched to the latest rev of everything.

Mine won't die 100% at the 4.26GB mark.. it would die sort of randomly (always under 4GB though).. but since I switched to using SFTP for big file uploads, it works like a charm (pushed 1TB of data up with no problem this morning).

Osx 10.7.4

Have just installed the new OSX Lion update (10.7.4) and re-tested since the release notes state that some SMB fixes are included. My problem transferring 4GB+ files though is still present.

Still, on a slightly unrelated note, at least I no longer have to un-tick 'Reopen windows when I log back in' every time I shut down my Mac. Yes!

[unholyeyebrows]

Still broken in latest beta.

I have just upgraded to 8.20beta4 and problem persists.

 

[unholyeyebrows]

I have just upgraded to 8.20RC1 and problem persists. Is anyone else seeing this problem between Mac OSX and FreeNAS 8.20? I'd like to try to diagnose this further but don't know what to try next.

Thanks
Nick
