Exchange 2013 log files filling the disk.

Question

Hi;

I am running two Exchange 2013 on DAG mode, I found that the partition where to store the log files is full due the the log files did not clean up automatically.

I run the following Exchange shell command and it is all good. What should I do?

Get-mailboxdatacopystatus

TestReplicationHealth -Identity Mailboxserver-1

TestReplicationHealth -Identity Mailboxserver-2

No error found, all pass.

However; when I look at the file folder where usually keep the copy queue, there are still a lot of files... some of them are .jrs files, a lot of them are the "E01008xxxx.log - E01009xxxx.log" files.

I know that this folder should be clean at all times, how can I clean up these files or resync this file?

C:\OS partition

D:\ to keep the mailbox.edb files

E:\ to keep the log files. A lot of log files since Oct 21st.

I also run the following command try to see if the VSS but it does not help

Diskshadow
add volume E: (this is the partition to store the log files)
create
begin backup
end backup

When I run this command.... Get-MailboxDatabase -Server EXSERVER01 -Status | fl Name,*FullBackup
The result is showing the

Name : Mailbox Database 1923107135
SnapshotLastFullBackup : True
LastFullBackup : 10/21/2020 7:02:06 PM

Name : Mailbox Database 1247985168
SnapshotLastFullBackup : True
LastFullBackup : 10/21/2020 7:02:02 PM

Name : MAILBOX01
SnapshotLastFullBackup : True
LastFullBackup : 10/21/2020 7:02:11 PM

Name : MAILBOX02
SnapshotLastFullBackup : True
LastFullBackup : 10/21/2020 7:02:16 PM

Please help if anyone know any other steps.

thanks!

Answer 1

Those are the Exchange Transaction logs and they should only be cleared by an Exchange Aware backup or by using Circular Logging.
Do not run any other type of backup against that drive.

1. What are you using for backups? If so, run a full Exchange Aware backup and the logs will clear
2. If you arent using a backup any longer ( since 10.21?) Then enable Circular Logging: https://learn.microsoft.com/en-us/exchange/configure-circular-logging-for-a-mailbox-database-exchange-2013-help Set-MailboxDatabase DB1 -CircularLoggingEnabled $True

WARNING: Do not enable circular logging if you are doing backups. Run a full Exchange aware backup. If you can not do that, then enable circular logging to clear the logs. Note that circular logging means you can not restore the database to the point of failure using a backup program

Thank you.

I am using Veeam backup, due to some Veeam server crashed on Oct 22nd, I took time to rebuild the Veeam server and the job for Exchange backup is running slow and sometime the Veeam is waiting for resources.

I have turned on the Application-aware processing on Veeam.

May be, I have to wait for the Veeam to complete the full backup, in the meanwhile; just monitoring the capacity of that particular drive.

Agree with AndyDavid, we can wait for the full backup then check if those transaction logs are truncated successfully.
If the full backup doesn't perform successfully, you can check the event logs to see if any related logs are generated for further analysis.
