Experts, What happens if the disk hosting an external journal of a filesytem running with data=journal goes bust. The Backstory ... I have been batteling with filesystem performance for some time now. Our setup is a HW Raid(6) with LVM on top and ext3 filesytems. Recently we added an SSD to our setup and have moved all the journals to this ssd. This has dramatically improved performance and especially reduced the interdependence between performance of different partitions hosted on the same RAID. http://insights.oetiker.ch/linux/external-journal-on-ssd.html I realy like the performance of this new setup, but I am not all that sure about the data security aspects of it. Especially after reading http://www.cs.wisc.edu/adsl/Publications/sfa-dsn05.pdf which suggests that damaged journals are the worst that can happen to ext3. any insights on this? cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland http://it.oetiker.ch tobi@xxxxxxxxxx ++41 62 775 9902 / sb: -9900 _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
