Hi. I have reported few weeks ago a bug on the Red Hat Bugzilla for CentOS 7 : https://bugzilla.redhat.com/show_bug.cgi?id=1341126 I had to restore a level0+level1 dump for my ownCloud server, but during the level1 restoration, xfsrestore showed many warnings and some directories/files were not restored. I recently tried to restore a more recent level0+level1 dump and I get the same results with other directories/files. I tried to figure out why and now I am able to reproduce the problem with a minimal test case. Here is the test case : Create a new XFS filesystem, mount it as "/mnt/test" Then in "/mnt/test" Create a directory "dira/" Create a file "filea" in directory "dira/" You should get : . └── dira └── filea Make a level 0 dump : xfsdump -l 0 -f /root/test0.dump /mnt/test Rename "dira/" to "dirA/" Create a directory "dirb/" in "dirA/" Create a file "fileb" in "dirb/" You should get : . └── dirA ├── dirb │ └── fileb └── filea Make a level 1 dump : xfsdump -l 1 -f /root/test1.dump /mnt/test Create a new XFS filesystem, mount it as "/mnt/restore" Restore (cumulative mode) level 0 dump : xfsrestore -r -f /root/test0.dump /mnt/restore/ Restore (cumulative mode) level 1 dump : xfsrestore -r -f /root/test1.dump /mnt/restore/ You get a WARNING : xfsrestore: WARNING: open of dirA/dirb/fileb failed: Aucun fichier ou dossier de ce type: discarding ino 526337 (No such file or directory in English) Directory "dirb" and file "fileb" is not restored : . ├── dirA │ └── filea └── xfsrestorehousekeepingdir ├── dirattr ├── dirextattr ├── namreg ├── state └── tree I attached test0.dump (level 0 dump), test1.dump (level 1 dump), debug0.txt (xfsrestore level 0 debug trace), debug1.txt (xfsrestore level 1 debug trace). I can reproduce it on CentOS 7 and Fedora 24. On Fedora 24, I used : xfsprogs-4.5.0-1.fc24.x86_64 xfsdump-3.1.6-2.fc24.x86_64 kernel-4.5.7-300.fc24.x86_64 Is there a bug in xfsdump/xfsrestore tools and cumulative restoration feature ? |
