Hello

After upgrading from Zarafa to Kopano 8.3.2.15 there are many warnings in the server log

ECFileAttachment: …seems to be an unsupported multi-stream gzip file (K-104)

I searched for an answewr but found nothing usable…

Any ides ?

Hello @bskoeln ,

this was originally reported in https://jira.kopano.io/browse/KC-104. you could try to recompress the affected attachments into single-stream mode files, e.g. gzip -d "$i" && gzip "${i%.gz}";

Hi
Thank you for the hint.

Using the unzip …gzip procedure shows following error messages :

1000 .gz has 2 other links - - unchanged

The attachments are stored on 2 mirrored disks.

" ls -l 1000.gz " shows a filecount of 3.

Does Kopano use any (hard)links ?

Do I have to react to the warning " ECFileAttachment…(K104)" at all ?

thank you
regards

No, Kopano itself does not use any hard or softlinks on attachments

when its just logged as a warning, then you do not necessarily act on it.
