Situation: all storage classes defined as `STRICT`; no `*` is used in storage class definitions. New chunkserver is added with new label, not defined in storage classes. As soon as...
I moved an HDD from one chunkserver to another (same label) so some duplicate chunks ended up on one chunkserver. That exposed several problems: * scanning is incredibly slow --...
Server Charts are not equalised on Y-axis and that makes it difficult to compare charts. If charts were equalised it would be easier to find slowest (or most active) server...
I use storage classes extensively. All of them are defined with specific Create, Keep and Archive goals pinning data to certain chunkserver labels. Default storage classes 1...9 are not used...
Erasuse coding is a space-efficient yet reliable way to store data in distributed manner. It is already implemented in Ceph, LizardFS and some other storage systems. See also https://github.com/lizardfs/lizardfs/issues/207
I can not add MooseFS as a _netfs_ type storage pool in _libvirtd_ (using `virsh` or `virt-manager`) hence it is not possible to use VM migration. (local _dir_ type pool...
Here is another practical problem. Most of our storage classes are defined like `-C C,C+S -K S,M` where `C` denotes high performance chunkservers equipped with enterprise class high endurance SSDs...
I'm investigating an error reported on one of the disks in the CGI and found the following in logs: ~~~~ 03:51:02 node01 mfschunkserver[225550]: hdd_io_begin: file:/var/lib/mfs/SSD400/ext4//86/chunk_000000000034E2A0_00000001.mfs - open error: ENOENT (No...
### What's expected (no `mfsmount` in `/etc/fstab`): ``` # mount -va; echo ::$? ## first time / : ignored /media/cdrom0 : ignored /media/usb0 : ignored /tmp : already mounted swap...
It would be nice if `mfshdd.cfg` ignore leading spaces in front of mount points. Thanks.
