Customer want to use it to store backups. The time of backup is very logs and sometimes it freezes with errors. Customer opened a SR to Veem. They replied that the issue with read data from storage. Customer performed test. No issues with write operations. But when read data from storage the reading process freezes on the OS, or tries to copy on a very low speed - 355KB/s and then freezes.
As checked by log, the user has permission for read and write :
<user_name>veeambackupOS03</user_name>
<permission_type>read and write</permission_type>
Check
the capture packet and analysis one request , host frequently send ACK
message to storage but the feedback packet from Storage don’t reach the
host . storage device keeps retransmitting TCP packets during the
period.
After 60 s , host RST disconnect TCP connection. The feedback packed should be drop on the link and cause that issue .
The MTU configuration is not same on switch and storage
It solve the problem after modify the MTU as 1500 on switch
