XFS will handle journaling issues at boot automagically, but a real fsck requires a bit of manual intervention. I just went through this today, and this is what you need to do: 1. Boot into rescue mode. Most people I know keep their boot and root partitions as ext3, so this should go smoothly even if you need to fsck your xfs partitions. 2. Unmount the XFS partitions you want to check. xfs_repair will do evil things to mounted partitions. 3. Run xfs_repair on your unmounted partitions. 4. Remount your partitions, and check lost+found. I strongly recommend running debsums --all after running xfs_repair on /usr, /var, and so on if any problems are found. 5. Reinstall any package that may have been corrupted. 6. Reboot--not always necessary, but highly recommended. Keep in mind that XFS only checks journaled metadata during mount--it doesn't do any filesystem integrity checks, even when one touches /forcefsck. Running xfs_repair once in a while is something I strongly recommend on home systems and workstations. -- Oh, look: rocks! -- Doctor Who, Destiny of the Daleks -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

How can I obtain the XFS file utilities - particularly xfs-repair - under Squeeze? Unless you're seeing XFS errors in your logs or on the console you don't need to run xfs_check or xfs_repair. Typically these tools are only used when an XFS filesytem becomes damaged badly enough that it won't mount, or when XFS logs serious errors. For the most part XFS is self healing but for the most serious errors, which usually result from defective disk and/or controller hardware. XFS journal replay after power outages and kernel panics will either delete or zero files and directories that weren't fully written at the time of the crash, but the XFS filesystem itself will be fully intact. What is it that leads you to believe you need to perform a filesystem check or repair on your XFS filesystem? Well, first of all, even if it is not needed now, it may be in the future. To answer your question, however, it was needed because the underlying array suffered a catastrophic failure, and has since been rebuilt. Having rebuilt the array, and knowing that at least some data had possibly been lost at the block device level, it is at least prudent to double-check the health of the file system structures. Indeed, xfs_repair found and repaired some corrupted structures. The files were extracted and re-written to the drive from storage using rsync.

It's not an instruction word width issue, but has more to do with the width of the data registers, and addressable virtual memory of 32bit platforms. I mistyped. Of course, I meant machine word width, not OS word width. And I use the term machine word width to mean register. Running a 32bit kernel, how do you process 64bit inode numbers in 32bit data registers? That would require a lot of code changes for a dying platform (ia32). Add the fact that i386 kernels have a maximum virtual address space of 16TB, which, not coincidentally, is the maximum 32bit XFS filesystem size. I think this last point is really the key to this issue, because if you were to add support to 32bit XFS for 9 exabyte filesystems, you'd only be able to mmap files up to the 16TB boundary. AFAIK, most I/O these days is done with mmap. If you have files or filesystems larger than your virtual memory space, you can't mmap anything beyond that address boundary. Is 32-bit dying or not? When I express an opinion that new installs should be 64-bit, someone takes me to task, and claim that 32-bit can do everything 32-bit can do. Yes, Stan. Making 32-bit Linux work with 64-bit inodes would require work. It would mean touching very many places in a fairly large codebase, and then a lot of testing would need to be done. Yes. I think it is worth doing, but, I am not a part of the XFS (or kernel) maintenance team(s), and I never will be. I am only a potential user. I guess my opinion is not worth much. I think I do have a problem sometimes when I post: I have a bit of a terminology gap with people like yourself. Please try not to hold me to a 100% literal interpretation. Certainly, correct my factual errors, as Ron Johnson did when I suggested the OP use tune2fs to cause an fsck to be performed on his XFS partition. So when I say something to the effect that it is a design error for some piece of code not to be able to handle what is essentially a data width problem, please understand that it is an opinion based partly on experience, partly on theory, and and partly on speculation. I don't pretend otherwise. I speculate. And I think, based on theory and speculation, that it is odd that no one has fixed what must surely be a problem for some users. Perhaps it isn't a trivial bug to fix. When the code was first designed, it was certainly a design decision. It was a decision *then*. But it is a *bug* now. Perhaps it isn't worth investing the effort to fix it. But it is certainly fixable. Whether you would use mmap for the first 16TB or not would just be another design decision. If you had a filesystem larger than that, obviously, you wouldn't be using mmap for a window larger than that. There would be potential wraparound bugs. Performance would probably be terrible. But it would allow someone to get the job done. MAA -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
