The DataDomain filesystem process (FS) on the source end for BOOST replication may crash if while performing the replication it fails to find destination directory or the file got deleted, with the logs showing a PANIC message such as below: PANIC: ddr/repl/lrepl_client.c: do_filecopy_send_file: 7564: filecopy ctx xxx:0: file /data/col1/xxx :: During compound path resolution an intermediate component is not found
There is a defect in the code for some DDOS 5.7, 6.0 and 6.1 releases by which any such errors on destination are not dealt with in the proper way, as they are not critical enough to force the sending DD to force a FS crash, and should retry the operation later instead.
Note there is no workaround to avoid hitting this bug, however the defect has been fixed in some upcoming DDOS releases, including: DDOS 5.7.5.6 and later DDOS 6.0.2.0 and later DDOS 6.1.1.0 and later If hitting this issue, a one time PANIC will occur, and the FS process should re-start automatically shortly afterwards. The fixed DDOS needs be installed on the DD acting as the source for replication only, although the recommendation is to have all replication peers on the same DDOS code whenever possible.
