I'm getting also related to vlog db
Control time="2021-05-30T11:40:33+03:00" level=error msg="[App] app: failed to create database: During db.vlog.open: Value log truncate required to run DB. This might result in data loss"
I needed to delete the content of AppData\Roaming\Wombat\db in order for Wombat to run again
Running on Windows 10 Pro
Having the same issue. Actually, why does it need a DB file of 2GB size?

When compressed, the directory contents are only 2-3 MB which makes me suspect that the process is writing repetitive information that bloats it up to the 2GB file size.
The error posted by @arkanmgerges matches in part ErrTruncateNeeded from BadgerDB. This error is only referenced in UpdateSkipList() during memtable creation.
// ErrTruncateNeeded is returned when the value log gets corrupt, and requires truncation of
// corrupt data to allow Badger to run properly.
ErrTruncateNeeded = errors.New(
"Log truncate required to run DB. This might result in data loss")
func (mt *memTable) UpdateSkipList() error {
if mt.wal == nil || mt.sl == nil {
return nil
}
endOff, err := mt.wal.iterate(true, 0, mt.replayFunction(mt.opt))
if err != nil {
return y.Wrapf(err, "while iterating wal: %s", mt.wal.Fd.Name())
}
if endOff < mt.wal.size && mt.opt.ReadOnly {
return y.Wrapf(ErrTruncateNeeded, "end offset: %d < size: %d", endOff, mt.wal.size)
}
return mt.wal.Truncate(int64(endOff))
}
Wombat will enter a state where it always crashes immediately during startup before the GUI is visible. The issue is resolved when the VLOG file is deleted from the AppData\Roaming\Wombat\db directory. Not sure if it has to do with the size (2GB) or something else.
Running v0.50 on Windows 10.
