Re: [firebird-support] Identifying damanged pages
Dne 29.3.2012 18:26, Ann Harrison napsal(a): 2012/3/29 Josef Kokešj.ko...@apatykaservis.cz Due to hardware malfunction, my database got damaged. GFIX (-v -f -i) tells me that a database has 1 record level error, 9 data page errors, 41 index page errors and 322 database page errors. IBFirstAid is your friend, as is backup. But before you backup the database, make a copy, use gfix to set it to read only, and back it up with gbak, using the -g switch to suppress garbage collection. If that works, you're unlikely to have lost data. Backup walks each table in storage order. The structures are linked, so a lost or damaged data page will show up. Luckily, the damaged table was one which rarely changes, so I was able to restore it from backup with good results. But I am noting down this suggestion for future reference.

Re: [firebird-support] Identifying damanged pages
Hello Josef, Look into firebird.log - there should be information about corrupted record/table. You can also check your database with FBFirstAID Diagnostician. Regards, Alexey Kovyazin IBSurgeon (www.ib-aid.com) Hi! Due to hardware malfunction, my database got damaged. GFIX (-v -f -i) tells me that a database has 1 record level error, 9 data page errors, 41 index page errors and 322 database page errors. I am not concerned about Index page errors - is seems obvious these will get fixed by a backup/restore cycle. But I would like to know: 1) What do the individual error types mean? 2) Is there a way to identify which tables were affected? I can live with damage to many tables, but not all of them.
