I lost my database in UI #100

Closed txx18 closed 3 years ago

txx18 commented 3 years ago

hello, . Yesterday I accidentally restarted my computer, and I found that some of my databases were missing. You can see I have only 5 databases here, but there are 8 directories in "dbmss". Snipaste_2020-12-27_18-17-59 Snipaste_2020-12-27_18-20-50

That mean I need to reload my another 3 databases, even if they may be broken. I would appreciate your help.

other information:

some of the databases were cloned from another orignally, and I use the original one for back up.
I renamed them when a database is online.

system inforamtion:

os: windows 10 v2004
neo4j version: 4.2.0 & 4.2.1
neo4j destop verson: 1.3.11

Hi @txx18, could you post the content of the databases.json file used by Desktop? You can find it by following these steps:

Press ctrl+k.
Type logs and press enter.
A directory will open up. Open the persist folder inside it.
You should be able to see the databases.json file there.

Not really sure what happened here, but I suspect the missing DBMSs are just missing in that file.

Thank you very much! I hava re-import my data. Next time I will check databases.json.

Thank you for the update, and sorry for the trouble!

I'm still not sure what could have caused this, but in Neo4j Desktop 1.4.0 we added a fix for Desktop removing entries from that file in specific circumstances, so this shouldn't happen again.
