Re: [Samba] SMB2 weird behavior with samba 3.6 PDC
What I meant to say is that Thunderbird downloads every message every time it is launched when I have max protocol = smb2 enabled. Without that line it checks the headers and is done. Even if it's not efficient I don't mind it downloading and caching the message once, but having to do so on every launch takes a lot of time and a lot of bandwidth. --- But SMB2 wouldn't affect the IMAP protocol. Is your local Thunderbird dir stored on a network share? If that's the case, then it's probably the same problem that others are experience about UID's not being resolved consistently (if at all)...that would cause possible file read/write problems and it might think it needs to d/l again. The thunderbird profile is stored on the users home share. This still seems like a SMB2 problem rather than a UID/GID problem since samba 3.6 works fine and thunderbird doesn't try and download every message again as soon as max protocol = smb2 is removed from smb.conf. Wouldn't a UID problem remain regardless of what the max protocol setting was? I don't have a windows server to test against, but surely this isn't acceptable behavior from a windows server. Hopefully one of the samba team members could help debug why all common browsers are unable to download files to a samba share. --- I'ts not just browsers. I was saving a large file (maybe that's the key -- a file that takes a long time to write -- was saving a 2GB image from from photoshop -- couldn't save it AT all.. Had to pull it out of the vfs_recycle to put it in place. I think you're right about many more programs being affected than just browsers. Notepad and thunderbird both seem to have serious problems and not just with large files. I was unable to open a very small html file with notepad and couldn't save my thunderbird preferences so long as smb2 was enabled. Have you opened a bug regarding any of your issues (specifically not being able to save files and them showing up in the samba recycle bin)? -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
