Hi! Having to interrupt my bluestore test, I have another issue since upgrading from Jewel to Luminous: My backup system (Bareos with RadosFile backend) can no longer write Volumes (objects) larger than around 128MB. (Of course, I did not test that on my test cluster prior to upgrading the production one :/ ) At first, I suspected an incompatibility between the Bareos storage daemon and the newer Ceph version, but I could replicate it with the rados tool: Create a large file (1GB) Put it with rados rados --pool backup put rados-testfile rados-testfile-1G error putting backup-fra1/rados-testfile: (27) File too large Read it back: rados --pool backup get rados-testfile rados-testfile-readback Indeed, it wrote just about 128MB Adding the “—striper” option to both get and put command lines, it works: -rw-r--r-- 1 root root 1073741824 3. Jul 18:47 rados-testfile-1G -rw-r--r-- 1 root root 134217728 3. Jul 19:12 rados-testfile-readback The error message I get from the backup system looks similar: block.c:659-29028 === Write error. fd=0 size=64512 rtn=-1 dev_blk=134185235 blk_blk=10401 errno=28: ERR=Auf dem Gerät ist kein Speicherplatz mehr verfügbar (German for „No space left on device”) The service worked fine with Ceph jewel, nicely writing 50GB objects. Did the API change somehow? Thanks, Martin |
