How to terminate running transfers

Symptoms

Transfers can't be terminated or hang indefinitely.

Description 

Transfers still have active sessions regardless of their status and can not be aborted from the WHM interface.

Workaround

This workaround should only be implemented if the transfer process no longer exists.

1. Check to see if the transfer session process still exists by looking for it in WHM's "Process Manager." or you can use the "ps" command with a "grep" command to search for the appropriate "rsync" process:

ps faux | grep rsync

This is an example of a transfer process:

1151961 delta19 20 0 21752 3624 956 D 7.9 0.0 0:02.51 /usr/bin/rsync --server --sender -vlHogDtpre.iLsfxC . -- .

2. If you can not find the process, identify the unfinished transfer's session ID:

-bash-4.2# sqlite3 /var/cpanel/transfer_sessions/whmxfer.sqlite "select sessionid from sessions where state != '100'"
cpthisisatestcopya202007210601035ab

3. Change the session's state:

-bash-4.2# sqlite3 /var/cpanel/transfer_sessions/whmxfer.sqlite "update sessions set state='100', endtime=date('now') where sessionid='1054056copya201407021337529eG8A76iJY'"

The states can be seen in this Perl module:

-bash-4.1# /usr/local/cpanel/3rdparty/bin/perl -MWhostmgr::Transfers::SessionBase -MData::Dumper -e 'our %codes = %Whostmgr::Transfers::SessionBase::SESSION_STATES; foreach (sort keys %codes){print "$_ $codes{$_}\n"};'
