Michael Hanselmann [Tue, 20 Mar 2012 16:57:12 +0000 (17:57 +0100)]
Stop acquiring BGL for LUXI queries

Short description: This fixes an issue whereby masterd would become
unresponsive on the LUXI socket, leading to client timeouts. While made
worse in 2.5, the underlying issue was already present in 2.4.

Longer description: Until now all LUXI queries would acquire the BGL
(big Ganeti lock) in shared mode. With the exception of OpNodeAdd and
OpNodeRemove, this was also the case for all opcodes before version 2.5.
In 2.5 we split OpClusterVerify into multiple opcodes, one of which
(OpClusterVerifyConfig) now acquires the BGL in exclusive mode. Whether
or not doing so is good is a separate discussion: OpNodeAdd and
OpNodeRemove, as of this writing, still require an exclusive BGL.
OpClusterVerifyConfig is run more often than OpNodeAdd or OpNodeRemove
in normal clusters, which is why we only recognized this issue in 2.5.

What would happen is that once OpClusterVerifyConfig tried to acquire
its exclusive BGL while it was actually held by other opcodes (e.g.
OpInstanceReplaceDisks), the locking code would not grant shared
acquires for the BGL, even when the exclusive acquire is removed from
the queue for a short amount of time after a timeout. This is necessary
to prevent lock starvation.

In this situation further LUXI queries requiring the BGL in shared mode,
e.g. OpClusterQuery, would block and the client eventually time out.
Over time they fill the client request workerpool's queue and at that
point even requests not requiring the BGL stop working. Once the
long-running operation(s) holding the BGL in shared mode finished,
OpClusterVerifyConfig gets it in exclusive mode and everything returns
to normal. LUXI recovers very soon too.

I'd like to thank Bernardo Dal Seno for his contribution to this bugfix.

Further fixes concerning drbd port release

Commit 3b3b1bc does not entirely fix the bug introduced in commit
f396ad8. It fixes consistency of config data in permanent storage, but
does not ensure consistency in data held in runtime memory of masterd.

The bug of duplicate ports is still triggered when LUInstanceRemove()
invokes _RemoveDisks() and this returns False (in case
call_blockdev_remove RPC fails). The drbd ports get returned in the
pool, but execution is aborted and RemoveInstance() is never invoked.

Due to the fact that port handling is not done with
TemporaryReservationManager, ensure that ports are released, only if
disk related config data is deleted.

In _RemoveDisks() release ports only if all RPCs succeed.

Extend _RemoveDisks() to include ignore_failures argument passed by
_RemoveInstance() to handle the ports appropriately.

Fix a bug concerning TCP port release

Commit f396ad8 returns the TCP port used by DRBD disk back to the
TCP/UDP port pool using AddTcpUdpPort().

However, AddTcpUdpPort() writes the config on every invocation,
using _WriteConfig(). This causes two problems:

 * it causes critical errors logged by VerifyConfig(), after the DRBD
   disk removal, and until the actual instance removal.
 * if the code following AddTcpUdpPort() fails, the port is already
   returned back the pool, which causes the port to have duplicates
   (inconsistent config).

AddTcpUdpPort() is invoked in three cases:

 * during InstanceRemove() through _RemoveDisks().
 * during InstanceSetParams() in case of disk removal.
 * during InstanceSetParams() through _ConvertDrbdToPlain().

This commit fixes the problem by removing the _WriteConfig() call from
AddTcpUdpPort(), delegate it to Update() via the
TemporaryReservationManager and ensure AddTcpUdpPort() precedes
Update().

12 years agoFix a bug concerning TCP port release
Dimitris Aragiorgis [Tue, 13 Mar 2012 14:48:58 +0000 (16:48 +0200)]
Fix a bug concerning TCP port release

Commit f396ad8 returns the TCP port used by DRBD disk back to the
TCP/UDP port pool using AddTcpUdpPort().

However, AddTcpUdpPort() writes the config on every invocation,
using _WriteConfig(). This causes two problems:

 * it causes critical errors logged by VerifyConfig(), after the DRBD
   disk removal, and until the actual instance removal.
 * if the code following AddTcpUdpPort() fails, the port is already
   returned back the pool, which causes the port to have duplicates
   (inconsistent config).

AddTcpUdpPort() is invoked in three cases:

 * during InstanceRemove() through _RemoveDisks().
 * during InstanceSetParams() in case of disk removal.
 * during InstanceSetParams() through _ConvertDrbdToPlain().

This commit fixes the problem by removing the _WriteConfig() call from
AddTcpUdpPort(), delegate it to Update() via the
TemporaryReservationManager and ensure AddTcpUdpPort() precedes
Update().

ganeti.initd: Add “status” action

his code was apparently specific to Red Hat. I hope this implementation
is more distribution-agnostic; after all “status_of_proc” is part of
LSB. Example output:
