Something like that. I tried to simply restart it but that didn't work. I've tried restoring a backup from a day ago and that doesn't seem to be working. I will continue to try b ackups but at a glance all the image files look larger than they should be which in the past has not been a good sign in terms of a working image. This may require assistance from someone with knowledge of the image/AIDA. But I will report back after I have tried all the backups or it is up again.

I finally succeeded on the 4th or 5th attempt. But frankly I am confused.

These are copies of the image/changes (i/c for short) that I found initially when the site was not responding.

The above are the most recent backup i/c. I never even tried them since they appeared to be direct copies of what obviously wasn't working.

And above are the other local backups we have, most recent to oldest. I tried each of these in turn starting from daily.1. I waited at least 2+ minutes after restarting the image in each case. The one where it finally worked and I stopped is daily.5. Now I didn't notice this until after it was working and I looked more closely but the images in daily.1-daily.6 all have the same size and date, in fact that date is a month ago. I don't know how the image save works in the squeak.org image, perhaps it was intelligent enough to note that there had been no changes and so there had in fact been no need to save since Aug 13?
Why did the 5th one work? I don't know. I don't believe the image has any external dependencies. Could it somehow depend on the changes file? Any other explanation I can come up with suggests at minimum it is time to reboot the system as a whole or that we have other more serious problems. Everything else seems to be working for now, even www.squeak.org is working. I'm just going to leave it alone for the time being.

P.S. Note the number 6 in the second column of each of those daily.1-daily.5 .image backups? That number indicates the links to the file data, the number of paths in the directory table that all point to the same file data. These 6 files are in fact actually just 6 directory entries pointing to the same data (they daily.6 one is the 'original'). This is exactly how our backup system (rsnapshot/rsync) is supposed to work. If a file has not changed from one backup to the next a hard link is created to the file rather than copy the file. This is actually done using the venerable cp command (see the -l option in the man page or other documentation). Anyway the point is that when the each backup took place, it was rsync's opinion that compared to the previous backup, the image file was unchanged, in which case it did not copy the file over the previously created hard link.
