Samba from source breaks users/sharing

sadpanda · 9. März 2024

I installed OMV6, had a bunch of shares up and running and wanted to attempt getting SMB multichannel running.... I built/installed Samba from source, gave 10GB cards in my Mint box and OMV static IPs, added server multi channel support = yes to extra settings, connected to 10GB switch and everything was flying at 2x... I shut everything down so I could rearrange the desk and on power on nothing was working.

Whats worse is I can't even get close to replicating it: on a fresh installs of both OMV6 and OMV7 basic shares work (no ACL just user/pass) but installing updated samba breaks shares. I can see the share but it does not accept credentials.

everything looks good in /etc/samba/smb.conf after upgrade ie shares are there, users are listed, changes made in GUI are being written to smb.conf

I've also tired installing samba right after OMV install (no existing shares etc) and no go.

OMV7 ships with a sufficiently new version of samba to do multipath but I could not get it to utilize both connections. smbstatus -v showed both IPs but only one had multiple ports and speed was slow.

FYI for testing I've got an NVME drive in the Mint box and simple 8 wide stripe on SSDs. I'm using

./configure --disable-cups --without-ad-dc --sbindir=/sbin/ --sysconfdir=/etc/samba/ --mandir=/usr/share/man/

during build

Any bright ideas?

Is it really necessary to build SAMBA from source? I've no direct experience of using SMB multichannel but this 3yr old post might offer some hints:

I would have thought testing from a windows client first might at least show the right pieces were in place for both software and hardware. As to whether a Linux client could work I have no idea, but i suspect you'd want to use kernel mounts as in mount.cifs rather than virtual mounts in desktop file manager via gvfs or whatever.

Yep, seen that a just about everything else on the ol web pertaining.

Up to Samba 4.15 smb multipath was considered experimental, after that it was enabled by default. OMV6 had a far older package so I built from source thinking it would help the issue.

OMV7 is packaged with 4.17.12 so I'll come back to this if I cant get resolution in another thread.

Jetzt mitmachen!
