1. the miscalculated progress occurs mostly on partial backups and a very
few incremental
backups. I assume it have no affect on the migration.
2.
- can't read attribute file: After reviewing the source code of
BackupPC_migrateV3toV4, I believe
that it also have no impact on migration. BackupPC_migrateV3toV4
"Compute the correct size by
reading the whole file" if it can't get it from the attribut file and
continue migration.
- Unexpected magic number: I can't find this in source code and don't
know what happens with this
3. directory 145.old still exist:
- 159837 files are calculated by "ls -R
/var/lib/backuppc/pc/gerhardpc1/145.old | wc -l"
- 119 files are calculated by "BackupPC_ls -R -h gerhardpc1 -n 145 -s
<sharename> /"
- so the migration failed. I'll try to migrate it once again.
4. can't create ./refCnt/needFsck.mig and ./refCnt/noPoolCnt:
- It looks like a filesystem error and not be triggered by program
logic. I'll try to migrate it
once again.
It would be great if someone could give feedback regarding this "Unexpected
magic number".
Thanks in advance
Matthias
