[Bug 361689] Re: hald segfault when using a raid volume
I've not had much time to look any further at this, and I haven't proposed my patch as a fix yet because I don't know if it is the right way to fix it. What I need to do really is send this bug report upstream, and also have a play around with a mdraid setup myself, but I don't have a clue how to set one of those up. Perhaps someone here could help me set one up ;) ** Changed in: hal (Ubuntu) Status: Incomplete = Confirmed -- hald segfault when using a raid volume https://bugs.launchpad.net/bugs/361689 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 361689] Re: hald segfault when using a raid volume
I think I can get you started. I mean, the first step to creating a RAID volume is to think it out. Where do you need redundancy? Where do you need speed? Then map out your partitions (especially if you have different sized disks). Remember that RAID will cause a slight (in the case of RAID0 or RAID1) to slightly greater (RAID5 or RAID6) processor and I/O load. That is the trade-off for getting better overall disk performance. Although it is supposedly not needed to RAID0 your swap partitions across disks (supposedly the swap daemon manages multiple disks very well) it doesn't hurt to do so and is an easy and safe way to get started with RAID. You might consider making this your test case. This page lays out mdadm and Linux RAID pretty well: http://ubuntuforums.org/showthread.php?t=408461 Basically: 1. format disks you want to use as RAID partitions 2. create a RAID array using mdadm --create /dev/md0 --level=[level] --raid-devices=[number of devices] [device1] [device2]...[deviceN] 3. assemble the array 4. format the array in the filesystem of your choice (like any other partition) 5. mount it like you would any other disk partition Pretty simple, eh? -- hald segfault when using a raid volume https://bugs.launchpad.net/bugs/361689 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 361689] Re: hald segfault when using a raid volume
How is it possible that this bug is only listed as Medium importance?!?!? I discovered what I think is this bug when I upgraded my system using system update. Upon a later reboot I found that I had no access to the system whatsoever. After trying multiple things to get back in from the root recovery console, I re-formatted, losing a lot of configuration. Fortunately, I am somewhat tech savvy and I didn't lose everything, but this cost me 2 days and will probably cost more. And for the average user, this could equate to complete data loss. I would think this would be a high importance bug since it disables a working system! Does anyone agree with me, or am I missing something here? --mobrien118 -- hald segfault when using a raid volume https://bugs.launchpad.net/bugs/361689 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 361689] Re: hald segfault when using a raid volume
Mobrien118, I agree that there should be some consideration of its importance. Maybe it isn't that big of a deal since few people have raid sets on their computers. It cost me several hours of rebooting and googling before I thought to boot into recovery console, install openssh and then log in with another machine to look at the dmsg output. I considered myself fortunate to have stumbled upon the solution here since the failure case is very confusing. If hald is so critical maybe there should be a better way of reporting these errors to the user. -- hald segfault when using a raid volume https://bugs.launchpad.net/bugs/361689 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
