Unable to mount /backups folder (Cifs)

[robi]

@p44 could be 2 things.. compare mount versions, which may have a different syntax.

make sure cifs is available on the new system, for ex if mount.cifs isn't available, it won't recognize the cifs parameter and error out.

if there are other cifs mounts available (any windows box) try making sure that works to validate cifs at least.

alternative might be smbfs.

cifs

Thank's @robi !

I've this situation:

/sbin$ apt-cache policy cifs-utils
cifs-utils:
  Installed: 2:6.8-1ubuntu1.1
  Candidate: 2:6.8-1ubuntu1.1
  Version table:
 *** 2:6.8-1ubuntu1.1 500
        500 http://it.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     2:6.8-1 500
        500 http://it.archive.ubuntu.com/ubuntu bionic/main amd64 Packages

Also mount.cifs is available.

If there are other cifs mounts available (any windows box) try making sure that works to validate cifs at least.

This step is not totally clear how to perform...

@robi Thank's Robi, I'll go deeper inside the problem fixing.

Just to check, is this a Hetzner storage box? If so be sure to have turned samba shares on at the Hetzner end (I had a similar issue and this resolved it for me)

[danigl]

I had the same problem. I use the following entry in fstab:

//XXX/XXX /media/backups_cifs  cifs uid=yellowtent,gid=yellowtent,username=XXX,password=XXX,vers=3.0,noperm 0 0

The target directory must be created first.

[p44]

@jdaviescoates Yes is Hetzner box. Works perfectly on two other Cloudron istances. Enabled "Samba shares" and "External Reachability".

On two works fine, another one no...

[p44]

@danigl Thank's a lot, the targeted directory is created first. Just a question: why you add the "vers=3.0" parameter?

[jdaviescoates]

@p44 said in Unable to mount /backups folder (Cifs):

Yes is Hetzner box.

It may just be an issue with Hetzner. As you've seen, recently my backup hetzner storage box somehow unmounted itself during a backup and I needed to restart for it to mount again.

Assume you've tried restarting your server already?

[p44]

@jdaviescoates Maybe is Hetzner side problem. I had a similar event few weeks ago and I opened a ticket to Cloudron support desk. I restarted server.

Also one week ago and also yesterday I had a similar problem.

For this case "Unable to mount /backups folder (Cifs)" I'm still investigating and I don't think is Hetzner side.

About unmounting problem, I was thinking to move to other storage service. Did you find any workarounds?

[girish]

@p44 Given Cloudron is just app on ubuntu, maybe you can try to mount it in a separate ubuntu server on Hetzner? At that point, Hetzner support should be able to help you out hopefully.

[p44]

@girish Totally agree with your suggestion. About the topic issue, the server where I running this specific Cloudron instance is not Hetzner.

But I just created a demo account to Wasabi to move forward and assure a backup.

Oh, that gave me an idea. Could it be that there is too much latency for the CIFS mount to work? Or maybe there is some configurable latency delay setting for mounting. Usually, CIFS/NFS etc works well only in same data center.

[p44]

@girish Thank's a lot Girish. Latency between two data centers is around 40ms... maximum 60ms... What's your idea?

Interesting. Got a reference for this?

I think I purposely chose a different location for my Hetzner Storage Box from my Hetzner VPS just for a bit more redundancy (in case the VPS location get destroyed somehow).

[p44]

@jdaviescoates Totally agree with this strategy. It could be interesting to chose a total different provider to achieve this goal.

I configured for Wasabi seems to be fast and resilient. But I have to well understand user policy and permissions.

When I use services like this, I'm always a little bit scared that folder can go public due permission problems.

[girish]

I was only guessing about latency, I don't have any special expertise here. I found this article https://www.redhat.com/sysadmin/using-nfsstat-nfsiostat that might help debug further.

Agreed. I'm going to investigate https://teuto.net/teutostack-openstack-public-cloud/?lang=en who apparently do S3 style object storage, who I came across here https://social.coop/@aligyie/105385317039616213

[robi]

@jdaviescoates Take a look at S3 from IBM for 25GB/mo free at IBM COS

p.s. I used to work on COS (formerly Cleversafe)

[jdaviescoates]

@robi thanks but the added context not mentioned is affordable storage space that is also powered by 100% renewable energy.
