Re: [lustre-discuss] Kernel/OS/Lustre version matching
Note also that 2.12.6 was just released and it shows the EL8.2 kernel in the ChangeLog, among many others: https://git.whamcloud.com/?p=fs/lustre-release.git;a=blob;f=lustre/ChangeLog;h=beefe94e2199eaa571f7a796c8219384fa8364c0;hb=refs/heads/b2_12 4.18.0-147.3.1.el8 (RHEL8.1) 4.18.0-193.6.3.el8 (RHEL8.2) 4.18.0-240.1.1.el8 (RHEL8.3) Since the same client code has to build on a wide range of kernels, the most straight forward answer is "if it builds it will work".

[lustre-discuss] Cannot move files to another directory
I tried to send this yesterday, but did not seem to get through. Try again now. Hi, We moved our MDT and MGT to a new storage device (DDN SFA200NV) this week. Everything appears to work but there is a very strange problem. We could not "mv" a file to another directory. This is for both old and new data. Here is an example: $ mkdir testdir $ dd if=/dev/zero of=testfile bs=1024k count=10 10+0 records in 10+0 records out 10485760 bytes (10 MB, 10 MiB) copied, 0.292493 s, 35.8 MB/s $ cp testfile testdir/ $ mv testfile testdir/testfile.new mv: cannot move 'testfile' to 'testdir/testfile.new': No such file or directory $ chmod 666 testfile $ ls -l total 10244 drwxr-x--- 2 liu liu 4096 Dec 10 08:12 testdir -rw-rw-rw- 1 liu liu 10485760 Dec 10 08:11 testfile $ rm testfile $ "mv" a file in the same directory works. I have an open case with DDN about this issue, but would like to know if someone here has any suggestions.
