Logs growing and took up entire log drive even with log backups I have a volume just for logs and another volume just for log backups.

The log volume kept  growing until it to run out of space even with log backups taken every 1 minute. 

Isn't the backups suppose to free up the space within the log file to be written over again?

It seems like this isn't happening.
run this query on your server

SELECT [NAME], 
       RECOVERY_MODEL_DESC,
       LOG_REUSE_WAIT_DESC,
       IS_PUBLISHED,
       IS_MERGE_PUBLISHED,
       is_subscribed
FROM SYS.DATABASES




if you have something different than NOTHING in the LOG_REUSE_WAIT_DESC there is where I would start investigating.

There are eight reasons SQL Server might report when it cannot truncate the transaction log

That is probably what is preventing the space within the log to be re-used.

For ACTIVE_TRANSACTION

I like to use the stored procedure called sp_whoisactive it will tell you what is currently running on your server.

or much simpler, just to see if there are open transactions:

DBCC opentran WITH NO_INFOMSGS


For LOG_BACKUP

Why is log_reuse_wait_desc saying LOG_BACKUP after doing a log backup?


  LOG_BACKUP really means “either you need to take a log backup, or the
  log records that were backed up were all in the current VLF and so it
  could not be cleared.”


There are eight reasons SQL Server might report when it cannot truncate the transaction log


  If your database recovery model is "full" SQL Server cannot reuse
  virtual log files unless all contained transaction log records have
  been backed up with a log backup. If a log backup is outstanding the
  log has to grow to accommodate new data changes. During this time you
  will see a log_reuse_wait_desc of LOG_BACKUP. Full or differential
  backups do not backup all transaction log records, so you need to run
  an actual log backup to allow for virtual log file reuse.


In this situation transaction log backups every minute I think it too high.

Find the number of VLFs in the transaction log.

I had this situation:
MY_DB (232 Gb) = 500,000 VLFs

and this is what I did (keeping each VLF = 8GB):

dbcc sqlperf(logspace)
go
use my_db
Go
select size/128,* from sys.sysfiles
dbcc loginfo('my_db')

-- updated my_db autogrowth to 4096Mb (chunk of 4 Gb)
DBCC SHRINKFILE(my_db_log, 1)
select size/128,* from sys.sysfiles
