[Samba] 32 seconds vs 72 minutes -- expected performance difference?

The verbose logs and network trace would tell us more. -- Aurélien Aptel / SUSE Labs Samba Team GPG: 1839 CB5F 9F5B FB9B AA97 8C99 03C8 A49B 521B D5D3 SUSE Linux GmbH, Maxfeldstraße 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg)

Here are a few operations from the log, and my observations on them: 1) Why is the log saying `SMB2` everywhere? Shouldn't it be saying `SMB3`? 2) Is this normal -- fs/cifs/smb2misc.c: Calculated size 157 length 156 mismatch mid 11907 3) Is this normal -- fs/cifs/misc.c: Null buffer passed to cifs_small_buf_release 4) Is this normal -- fs/cifs/readdir.c: index not in buffer - could not findnext into it fs/cifs/readdir.c: could not find entry 5) This definitely seems like some error, right? -- fs/cifs/smb2maperror.c: Mapping SMB2 status code 0x80000006 to POSIX err -61 There is also another data point which _might_ be relevant. It _seems_ that "systemd-resolved" is randomly crashing on the server , possibly because of the mounted samba share. Caveat: I am not completely sure about the correlation between samba mount and systemd-resolved crashes. Nevertheless, I had already asked this question on StackExchange at https://askubuntu.com/questions/1117842/systemd-resolved-crashing-with-failed-to-set-up-mount-namespacing-invalid-argu if you feel that this might be relevant. Further, I can confirm that systemd-resolved had NOT crashed when the following logs were obtained: ## OPERATION 1 - `ls debug.log` -- simply listing a single file. Does anything seem wrong with this?

[Samba] 32 seconds vs 72 minutes -- expected performance difference?
Is plain `ls` fast? Are you using root on the server and some other user on the client? I dont think it applies to your situation, but had a very similar situation years ago. `ls` ... very fast `ls -la` ... very very very slow The filesystem was connected to MS Active Directory (maybe via likewise) and was doing the permissions lookup for user,group,other rwxrwxtwx for each of the groups the current user was a member of by querying AD each time.

Does > anything seem wrong with this?This is going to be disapointing but we don't see the error that gets added in the stats in this log extract. Have you checked your samba logs as well? There might be useful information in there (might have to increase "log level" in smb.conf, it can go up to 10 but that will generate a *lot* of data). If you still don't want to share the network capture you should at least try to open it yourself in wireshark, it would save everyone time. You can find out the protocol negotiated by filtering for smb2.cmd == 0 And looking at the Response SMB2 > Negotiate Protocol Response > Dialect in the lower panel. Note that if you re-mounted during the capture or if some error happened the kernel might have tried to reconnect automatically and you will see multiple Req/Resp. You can filter for packets with errors like so: smb2 && smb2.nt_status != 0x80000006 && smb2.nt_status != 0 You can ignore "MORE_PROCESSING_REQUIRED" and ioctl error "FS_DRIVER_REQUIRED" as well. They will show up on every reconnection. Also, please attach files or disable word-wrapping when you send logs in the future.
