Hi Christian, thanks for the reply, I am glad to hear that someone else is using it.
I haven't had a problem using scratch volumes. Could things be faster? Sure, but all the work is getting done. And I am expecting ext4 to improve things with extent allocation. I am also changing the hardware for the db which should speed things up too.

Hi Colwell, I'm using EXT4 on 2 TSM Servers. One of them do I have full controll of and it works fine. The other Linux system to I only see twice a year. But the customer normally drop me emails if he got something wrong. But the same problem with EXT4 as with EXT3 is that you need to pre allocate all volumes before and not let TSM create them on-demand.

Hi, I am running 2 6.1 servers on rhel 5.5. I am doing a lot of doing dedup. All primary storagepools are devicetype file. Current I have 10 16TB ext3 filesystems on raid 6 Sata. All volumes are scratch allocations. I have another 96TB ready to go. I haven't made the filesystems yet. So my question is if anyone is using ext4 yet as the filesystem type for TSM storagepools. >From my initial reading, I think the extent allocation feature would be very useful. See http://en.wikipedia.org/wiki/Ext4 I opened a pmr today to ask if IBM would support servers using ext4, and they just called back! They will support servers using ext4 for file storage. (But not for client backups yet). Also, is anyone using ext4 for the database? Thanks, Bill Colwell Draper Lab
