So, now decide for your own, if you consider LVM stable - I would ;) Regards, BodoHave you lost any disc (i.e. "physical volumes") since February? Or lost the meta-data? I would not recommend anyone to use LVM if they are less than experts on Linux systems. Setting up a LVM system is easy: administrating and salvaging the same, was much more work. (I used it ~3 years ago)
My read on LVM is that (a) it's one more thing for the admin to learn, (b) because it's seldom used the admin will be working from documentation if it has a problem, and (c) there is no bug-free software, therefore the use of LVM on top of RAID will be less reliable than a RAID-only solution. I can't quantify that, the net effect may be too small to measure. However, the cost and chance of a finger check from (a) and (b) are significant. -- bill davidsen [off-list ref] CTO TMR Associates, Inc Doing interesting things with small computers since 1979
