This is one my biggest worry about it. Indeed I always stop the daemon manually and check everything's fine before starting the shut down procedure.

Odd, systemd should allow time to sync before powering down.  If there are any systemd experts reading this, please let me know if the service file asd uses is kosher:

[Unit]
Description=Symlinks and syncs user defined dirs to RAM thus reducing HDD/SDD calls and speeding-up the system
Wants=local-fs.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/anything-sync-daemon sync
ExecStop=/usr/bin/anything-sync-daemon unsync

[Install]
WantedBy=multi-user.target

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

I get dropped to login prompt when booting, am using systemd... systemd does take a few goes before it settles down. If you need any output let me know in the mean time I will keep testing.

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

So you're still meeting with failures?  Can you post your asd.conf and how large are the dirs you are asking it to sync?

Do not sync /var/log or bad things will happen.

Would have been real handy to sync /var/log when using an SSD drive....

You can and should link to the posts you're referring to, as users can set the number of posts per page - for me this thread is only 2 pages long.

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

@karol - Thanks for the reference for users to see.  I t is too bad that systemd gets pissed off when syncing the dir in question.  If I knew more about it, perhaps delaying the start of asd would remedy the problem.

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

I keep /var/log synced to RAM, and I don't have any problems (as far as I know). I have no idea why, though, I guess my system isn't supposed to like this...


Sometimes, when I'm trying to get any audio software or hardware working with my system, I wonder why I ditched Windows. But every time I work at a windows computer, I remember it again.

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

On the 3.4 I noticed that if I stop the daemon manually then the cron job still sync my folders. Have this been solved on 3.6?

Now I've upgraded to 3.6 and still have to test. Regard the installation pacman said me:

WARNING:

You MUST compare your existing /etc/asd.conf to the one provided
by this package or else new features will not work and you risk breakage
of the software in general!

But no /etc/asd.conf.pacnew was there...

Interesting hypothesis.  Seems like systemd would not halt the machine until the processes it starts finished though.  Do you want to take the lead on following up this in an email with one of the systemd devs?  Perhaps post to their mailing lost on behalf of the project?  smile

1)  Yes, solved.  Please see the change log on github or in the source tarball for details.
2)  This is only true if pacman detects a change from your version.  I do not understand how this situation is not true though since you certainly have defined something in the WHATTOSYNC array.

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

2) It's simple because yesterday, after many unwanted sync I decided to empty the WHATTOSYNC array, so everything's fine wink

I'll go on testing the new version big_smile


About the shutdown: since the last pacman -Syu sending SIGTERM to all processes fails in my system and I still haven't detect why. This was before start to trying asd, but I'm not sure if it may effect also asd. So that's why I prefer sync and turn off asd before halting. I also noticed that if I copy one or two GB to ram and heavy modify them, sync take quite much time (naturally due to the HDD writing speed) and as Mr Green said there may be no such time available during the shut down procedure.

I'm also having some troubles to make asd sync the same folders that services like Dropbox do. It seems that Dropbox doesn't like too much the backups and the symlinks.. I don't know if something can be made for this..

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

No idea how Dropbox works.  Are you pointing it to sync the source or the linked source that asd creates?

Re: anything-sync-daemon - keep ANYTHING in tmpfs and sync'ed

DB and similar cloud services keep the contents of a folder synced with their servers so your files are always backed up and you can access them from everywhere.

Now asd is syncing some subfolders that Dropbox already checks creating symlinks and backups. When doing this DB drives crazy with great CPU and disk usage. Moreover during shut down the removed backups can't be synced by DB as obviously there's no time. Surely a solution will include to move the backups to an asd system directory, but I have to investigate how DB works with symlinks.

You can uninstall it anytime.  I gave it a post remove function to unsync thus restoring your synced dirs automatically.

Same here, nothing bad has happened here... yet.

If it's shutdown that's the problem, it could be because my shutdown is delayed by my external hard drive - it takes a few seconds to unmount since it's usually on power save.
