Good to hear. Does your my.cnf file not have a "[mysqldump]" section? That's
where mysqldump looks for its settings.
If you run "mysqldump --help", it'll tell you where it looks for that ini
file, and further down it'll tell you what it's actually using
settings-wise. 
Oh, and make sure that you only have one of those ini files, so that one
doesn't overwrite the settings in the other ;-)

Re: [rt-users] MySQL backups of RT 4.4.1 truncated

It's fixed!!! Recap: large RT database (host Ubuntu 14.04LTS, database server 
MySQL 5.7.x on Windows Server 2012). Backup .sql files became truncated at 
~18GB when the database is easily 20GB.

It looks like (for whatever reason) the max_allowed_packet option is not 
carrying over to the backup scripts. I re-wrote my backup options as:

-u USER -h HOST --max_allowed_packet=512M --single_transaction > output.sql

That solved it.

And I get a full backup of the file. Probably my own fault, but wanted to share 
the information. I'm now getting 19.5GB+ backups. Thanks to everyone!

The problem has become more interested. Switching from --results-file to > 
exposed the max packet problem but now, I can't seem to get around it. I 
currently have my max_allowed_packet set to 1024M and it's still dying. I have 
the approximate row & attachment ID where it's failing and if I'm reading it 
right it's a 110K PDF file. I tried upping it to 2048M but apparently that 
isn't allowed as the value in MySQL doesn't go any higher.

2017-01-28 Thread Cena, Stephen (ext. 300)
It looks like I've found the problems. To recap: I've got MySQL Server 5.7 on a 
Windows Server 2012 host running an RT database of ~20GB. My mysqldump backups 
started becoming truncated for some reason.

I'm not sure how much of this is relevant to Windows, but it turns out this is 
what was happening:
Using the --results-file= instead of > was masking a "max_allowed_packet" 
problem. Once I switched my backup scripts to use the redirect it appeared. The 
backup is still crashing, but the size is larger now. I'm tweaking my 
max_allowed_packet size to get it stable.

Also, I saw a note that if you're dumping data to the local host that using 
"shared memory" is faster than a TCP connection to local host. I'm tempted to 
try it but if anyone has any experience there I'd appreciate it.

Thank you to everyone who helped debug this with me. I hope this helps someone 
in the future!

Small update: I was able to fix the system errors for logging. While the 
err.log doesn't contain much, there were two telling entries:

2017-01-26T01:12:29.975366Z 1622 [Note] Aborted connection 1622 to db: 
'rt_service' user: 'backupdb' host: 'localhost' (Got an error writing

'rt_service' user: 'backupdb' host: 'localhost' (Got an error writing

That's my MySQL backup account which only is used to dump the files and that's 
my affected database.

I've got an active MySQL 'support request' out there: 
https://forums.mysql.com/read.php?28,654543 , I'll be adding this shortly.

Something is definitely disrupting the connection.

Excellent point. The MySQL TEMP folder was moved, but not the operating system 
ones. I'll see if I can move the OS temp locations to the larger drive today & 
see what that gets me. I've just gotten the last 30 lines of the "attachments" 
table .sql file so I'm checking that to see if maybe there's anything in the 
text that might cause a stop. Still looking into this one guys. Thank you for

There are temp files and temp files.  The files you moved may not be the ones 
you need to move.  You might try observing the free space as the backup 
proceeds and see what it is filling with.  That might give you a clue of which 
set of temp files need moved.  I.e. rt vs. web vs. MySQL vs. System vs. 
whatever.  Each may define temp files in a different way.  Config file vs. 
registry variable vs. environment variable vs. different environment variable 
vs. command line parameter vs. whatever.  We programmers can get creative.

As to the question you asked about indexing, I don't know.  That should be 
asked to the list at large.

All the backups I'm doing are local to keep performance high. I sadly lost the 
"discussion" to keep the MySQL server on a Linux machine. What we're going to 
try is the following:
We're snapshotting/backing up the system at regular intervals so I will always 
have a backup of the .sql files. I'm going to move the MySQL TMP folder to the 
larger drive to see if that solves the issue. I think you might be on to 
something with the drive issue as it looks to be the only consistent factor. 
I'll update as I know more.

Just FYI:
When windows copies files between drives, I believe it copies them to a temp 
area first before copying the temp area to the destination.
It probably does this to avoid writing a partial file when running out of 
space.  Because it causes a doubling of data transfer, it is stupid, but then, 
it is Microsoft Windows.

If your backup process includes copying the result across drives, this could be 
the source of the problem.

I just looked into this now. Got a little swamped yesterday. It looks like the 
system is using the OS drive which barely has 19GB free so it's possible that's 
what's tripping it up. I checked the error log & the only errors I'm seeing are 
dropped packets from my RT systems around the time of the backup (which would 
make sense if they aren't stopped). I have a 20GB partition that I can use to 
move the temp tiles to. I'm also going to talk to our VM admin about getting a 
"scratch drive" added. I'm running another PowerShell "grep" on my attachments 
backup file as the sizes from the 18th and the 19th are identical. With the 
volume we do, I don't see how that's possible. The "everything else" .sql file 
shows expected growth.

Folder compression can slow things down, but should not cause an issue.

What about temp/scratch space?  If you are making temp files on a different 
disk that is low in space, failure there could cause the problem.  Check the 
free space of all accessible drives, and check where temp files go.

Jeff - No limit that I'm aware of. If I look at a VM backup in December, the 
SQL files actually hit 19GB+ versus the "18 and change". The only other

because the backups are getting so large their filling the drive. I could 
temporarily disable it to see if that is factoring into it, but I've bene using 
it all along without issue. The real kicker is I didn't notice the issue soon

Another stab in the dark.  Is the destination file of the backup hitting a size 
boundary?  What size is it?  Anything close to a power of 2 would be 
suspicious.  Also, free space on the destination and on the temp/scratch areas 
need to be large enough.

You can check your RT database to see whether 64MB is enough by running

select max(OCTET_LENGTH(Content)) from Attachments;

in the context for your RT4 database. If that query comes up with anything 
above 48MB, I'd raise that variable to a suitably higher value.

I had that issue initially, and changed the value to 64MB. It was originally 
4MB, then I increased it to 16MB, it's been at 64MB for some time.

# The maximum size of one packet or any generated or intermediate string, or

#max_allowed_packet=16M

It's the oddest thing. The backups were working perfectly through most of 
December. Sometime between the week of Christmas and now it seems to have 
"blown up". As a work around right now, I've split the backup in two pieces: 
just attachments, and everything else. That appears to be working but I can't 
seem to explain why this has happened.

Hello Stephen,

just a stab in the dark, but could you please check the value set for 
"max_allowed_packet" in the mysqldump section of /etc/mysql/my.cnf (or whatever 
your my.cnf file is named)? If you try to dump mysql objects that are larger 
than this size, mysqldump will stop; probably with a message like "mysql server 
has gone away". You can raise that value for mysqldump just by editing that 
file; no server restart is required.

I'm currently running RT 4.4.1 on Ubuntu 14.04 LTS with MySQL 5.6 on Windows 
Server 2012. Recently, we enabled full-text indexing in native MySQL & 
everything is great. After doing some work on the server over the weekend, I 
discovered that the .sql files being generated for the backup are being 
"truncated" after the attachments table (~18-19GB).  After reviewing your 
documentation (https://docs.bestpractical.com/rt/4.4.1/backups.html) I realized 
my mysqldump command was incorrect. I'm working in a lab environment now to see 
how I can optimize/change my script to more closely match yours. The only 
thought I have right now is to exclude the data from the AttachmentsIndex as 
that would get rebuilt on restoration anyways. Is there any other reason that 
the backup would just "stop" after the attachment table? I apologize if this is 
beyond the scope of the forums thread.



Thank you in advance!

Re: [rt-users] MySQL backups of RT 4.4.1 truncated

2017-01-19 Thread Thomas Bätzler
Hello Stephen,

 

just a stab in the dark, but could you please check the value set for
“max_allowed_packet” in the mysqldump section of /etc/mysql/my.cnf (or
whatever your my.cnf file is named)? If you try to dump mysql objects that
are larger than this size, mysqldump will stop; probably with a message like
“mysql server has gone away”. You can raise that value for mysqldump just by
editing that file; no server restart is required. 

 

HTH,

Thomas Bätzler

Betreff: Re: [rt-users] MySQL backups of RT 4.4.1 truncated

 

I just ran a test with the attachments table “ignored”, and the backup
worked perfectly. As a “sanity check”, I also ran mysqlcheck on the schema &
no errors were found. Should I split my backup job into two pieces, or is
there a better way to get a backup all in one shot?

I'm currently running RT 4.4.1 on Ubuntu 14.04 LTS with MySQL 5.6 on Windows
Server 2012. Recently, we enabled full-text indexing in native MySQL &
everything is great. After doing some work on the server over the weekend, I
discovered that the .sql files being generated for the backup are being
"truncated" after the attachments table (~18-19GB).  After reviewing your
documentation (https://docs.bestpractical.com/rt/4.4.1/backups.html) I
realized my mysqldump command was incorrect. I'm working in a lab
environment now to see how I can optimize/change my script to more closely
match yours. The only thought I have right now is to exclude the data from
the AttachmentsIndex as that would get rebuilt on restoration anyways. Is
there any other reason that the backup would just "stop" after the
attachment table? I apologize if this is beyond the scope of the forums
thread.

 

Thank you in advance!
