Degraded performance for users with /home hosted on NFS server

**xnobodyx** · August 20th, 2024

Hello,

Our setup has Ubuntu 22.04.4 desktops with /home mounting from an Ubuntu 22.04.4 NFS server (storage in a zfs pool). Performance has degraded when logged in to any of the desktop machines, especially after opening processes that read/write to the home directory (web browsing, opening a terminal etc). This seems especially noticeable the first few minutes after logging in (nfs files are first accessed, but will continue happening on and off intermittently. The same issue happens across all desktops and desktop hardware tests have shown no issues. SSH logins to the desktops can take a while as well (perhaps due to checking keys in /home)?

No noticeable entries appear in journalctl logs when these issues occur but perhaps looking at the wrong logs?

Created a test user on one of the machines, with a local home directory and the account doesn't seem to exhibit any performance issues.

The NFS server seems stable - zfs status shows all drives ONLINE and no repairs needed in the last scrub. Looking at nfsstat and nfsiostat doesn't show any glaring issues. Testing storage performance on the server seems alright as well.

Fileserver Details:

Linux fileserver 5.15.0-118-generic #128-Ubuntu SMP Fri Jul 5 09:28:59 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
IP Address: 10.10.60.1

/etc/exports:

Code:

/tank/share       10.10.0.0/16(fsid=0,rw,async,no_root_squash,insecure,no_subtree_check)

Desktop Details:

Linux desktop1 6.8.0-40-generic #40~22.04.3-Ubuntu SMP PREEMPT_DYNAMIC Tue Jul 30 17:30:19 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
10.10.60.51 etc.

NFS entries in /etc/fstab:

Code:

fileserver:/opt       /opt            nfs4    rw,nodev,soft 0 0
fileserver:/home      /home           nfs4    rw,nodev,soft 0 0

Will run some further tests/benchmarks but wanted to post the initial config to see if there were any thoughts or suggestions. any help is greatly appreciated, thanks

Is other NFS storage slow too?
Are getent lookups slow?
Are DNS lookups slow?
Are any snaps being used?
Are the times all synchronized between all systems?
Is NFS4 with Kerberos being used?

For a long time, snaps broke when any NFS was used. I found their workaround for HOME directories completely unacceptable - forcing NFS HOMEs to be mounted under /home is just foolish. That removes many things that have been solved on Unix systems for decades from working. Snaps need to allow HOME directories to be anywhere with local configuration, if LDAP isn't enough "proof" for where HOME directories should be allowed. Whatever. The Snap team has refused to move on this, breaking corporate installs of Ubuntu. Nobody is forced to use Ubuntu after all. There are other distros without this issue.

Of course, your issue may have nothing at all to do with snaps, so perhaps that rant can be ignored.

Thanks.

1. Yes, other NFS storage ( /opt ) appears slow as well.
2. No apparent getent issues (tried groups/networks/services)
3. DNS lookups don't seem to have any problem (dig)
4. Yes firefox is a snap
5. times appear to be synced (timesyncd syncing with ntp.ubuntu.com)
6. Kerberos is not being used, just NFS4

NFS home directories are being mounted in /home . (i did run into the snap issue when creating the local account with a local home directory not in /home/ for testing)

Can you rule out ZFS as the problem? Create a little ext4 data area and export that via NFS?
Do you have IO performance data that can be compared between local, ZFS and ext4 NFS storage? Something like fio is commonly used for this. Wouldn't hurt to compare NFS and rsync performance between the two systems too, just to get a feel for the difference in performance. In theory, NFS without Kerberos should be much faster - probably to the network speed limit or to the storage speed limit if it is lower (non-SSD).

will try all those tests, thanks

I can't tell if this is a new deployment or not from your post. If you previously were on high speed local storage the answer is simple. If you are running your /home NFS share over Wifi it will be slower no matter what. Even a gigabit hard line will be noticeably slower than local storage ssd style. It can also be limited by the speed of the network uplink on the server itself. Even if you have 10gbit stuff around if the server is uploading a 1gb line then that is the best it will get.

Check for this type of thing before searching deeper I'd think. Way to look at it. Don't bother jumping to change the light bulb unless you make sure the light is plugged in first.

thanks for the reminder. i should have mentioned that i suspect this might be a network level issue, but was worried i might have made an obvious mistake with the NFS config. this is not a new deployment, the server and desktop config hasn't changed, but the desktops have moved to a new location. desktops and fileserver are using wired connections with 1Gb/s NICs. just did some testing from another server on the same rack as the fileserver and network speeds look fine there, but the desktop speeds aren't good at all. will investigate further.

running iperf3 --client fileserver --bytes 2G from the other server:

So this is the 1-time that it really is a network issue?
Check the routing. Perhaps someone in the network team made a mistake?

turns out this was a networking issue after all. even though they are in the same building the fileserver and the desktops are on different switches with different fiber connections to the gateway. the fiber connection to the server switch is bad. thanks for all the posts and assistance.
