AFP TimeMachine share spinning up every 30 minutes

[SnickySnacks]

Been trying to work out how to prevent this.

I have a time machine share set up and confined to a single disk.

Nothing else is on that disk.

 

If I do not connect my laptop to the server, it spins down as normal.

However, once I connect my laptop the disk will spin up every ~30 minutes or so, even after the laptop is powered off/wifi turned off.

inotify says the file being accessed is:

/mnt/disk9/TimeCapsule/.AppleDB/ MODIFY __db.002

 

lsof lists the files open on that drive as all being open under shfs:

shfs      2139        root    4u      REG                9,9        0        11 /mnt/disk9/TimeCapsule/.AppleDB/lock

shfs      2139        root    5w      REG                9,9    2379        12 /mnt/disk9/TimeCapsule/.AppleDB/db_errlog

shfs      2139        root    7w      REG                9,9    2379        12 /mnt/disk9/TimeCapsule/.AppleDB/db_errlog

shfs      2139        root  14u      REG                9,9 10485760      76101 /mnt/disk9/TimeCapsule/.AppleDB/log.0000000012

shfs      2139        root  16u      REG                9,9  8863744        20 /mnt/disk9/TimeCapsule/.AppleDB/cnid2.db

 

 

My laptop is powered off with the wifi turned off, so I'm fairly sure it's not the laptop doing it, plus checking TimeMachine itself indicates that it is not making backups during this time.

 

This seems similar to the issues seen here:

I haven't been able to catch anything interested in lsof other than the above. I tried to do an inotifywait -> lsof to catch what is accessing the file, but didn't get anything different than normal when doing:

inotifywait -r -e modify /mnt/disk9/TimeCapsule ; lsof | grep disk9

 

I'm open to suggestions on how to debug this or if it's just a quirk of the shfs program or something.

Needless to say I'd be really happy if it didn't do this.

 

Attached diagnostics for good measure.

 

Any ideas?
