[flexbackup-help] Afio problem

[Lionel D. <lio...@fr...>]

i use flexbackup 1.2.1 on a debian sarge.
I do backup with afio and bzip2 on travan tape 4/8 Go Seagate STT8000A.

All my backup process fine :

afio: 145m+690k+0 bytes written in 346 seconds. The operation was successful.
Kilobytes Out 149170
Kilobytes Out 149170

But when i want to decompresss with flexbackup -extract command, afio tell me :

| Logging output to "flexbackup.extract.200608181908.log"
| Trying "mt defblksize" instead of "mt setblk"
