failed to read ....: buffer size is too small

[eleaner]

version 1.49
I have a cluster with:

• three masters
• ten volume servers
• three fillers on Cassandra

when mounted
./weed mount -dir /home/kisiel/weedfs/ -filer 192.168.1.35:9888 -allowOthers
I seem to be able to write data into the cluster
I can read/download data using a web browser
but I cannot read the data from a mounted folder
even copying data from seaweed to seaweed does not work
cp: error reading 'linux_amd64.tar.gz': Input/output error

filer is reporting errors like this one:
