Hi, I am trying to xrdcp file into a small EOS instance by specifying the master MGM node in root:////eos/tier1dev/cta/testfiile. I have set the three registered filesystems of this node to read-only. However EOS doesnt appear to redirect to the FSTs of the other nodes which have filesystems in read-write mode. Can you please tell me which flag(s) I need to set? Many thanks, George ---

Ah sorry, that framework does not show URLs, if they are not properly quoted … Do you use URLs like > root://hostname//eos/dir/path ---

HI Andreas, Thanks. Yes, I use the URL like root://hostname//eos/dir/path which works if the node’s fs is in rw but not when it is in ro or off. George ---

Your filesystems have also to be shown as online: ```auto ┌────────────────────────┬────┬──────┬────────────────────────────────┬────────────────┬────────────────┬────────────┬──────────────┬────────────┬────────┬────────────────┐ │host │port│ id│ path│ schedgroup│ geotag│ boot│ configstatus│ drain│ active│ health│ └────────────────────────┴────┴──────┴────────────────────────────────┴────────────────┴────────────────┴────────────┴──────────────┴────────────┴────────┴────────────────┘ eos5dev.cern.ch 1095 1 /data/01 default.0 local::geo booted rw nodrain **online** no smartctl ``` Then you have to make sure, that you set the nominalsize for your space and that all the nodes/filesystems are enabled and each filesystem has a geotag definition. ```auto eos space set default on eos space config default space.nominalsize=1T ``` ---

Ah sorry, didn’t see your reply. I don’t understand really the question. If you have a filesystem in ro, then it cannot write there. Do you say, if you have one in ro, it does not select another one in rw mode? ---

The simplest is, if you paste: ```auto eos geoshed show tree eos fs ls ``` ---

I am basically trying to test the case when an FST node is down, i.e. its filesystems unreachable. Presumably EOS has a way to redirect the xrootd write to another FST node. I am trying to figure out what flags are needed to enable this. Pleasee the pasted output from the two commands ## eos geosched show tree ┌─────────┬──────┬────┬────────────────────────────────────┬────────┬─────┬───┬──────┐ │group │geotag│fsid│ node│branches│leavs│sum│status│ └─────────┴──────┴────┴────────────────────────────────────┴────────┴─────┴───┴──────┘ default.0 2 3 5 └───▶ rack1 1 3 4 ├──▶ 1 [host-172-16-112-243.nubes.stfc.ac.uk](http://host-172-16-112-243.nubes.stfc.ac.uk) 0 1 1 DinRW ├──▶ 4 [host-172-16-103-55.nubes.stfc.ac.uk](http://host-172-16-103-55.nubes.stfc.ac.uk) 0 1 1 DinRW └──▶ 7 [host-172-16-112-247.nubes.stfc.ac.uk](http://host-172-16-112-247.nubes.stfc.ac.uk) 0 1 1 DinRW ## default.1 2 3 5 └───▶ rack1 1 3 4 ├──▶ 2 [host-172-16-112-243.nubes.stfc.ac.uk](http://host-172-16-112-243.nubes.stfc.ac.uk) 0 1 1 DinRW ├──▶ 5 [host-172-16-103-55.nubes.stfc.ac.uk](http://host-172-16-103-55.nubes.stfc.ac.uk) 0 1 1 DinRW └──▶ 8 [host-172-16-112-247.nubes.stfc.ac.uk](http://host-172-16-112-247.nubes.stfc.ac.uk) 0 1 1 DinRW default.2 2 3 5 └───▶ rack1 1 3 4 ├──▶ 3 [host-172-16-112-243.nubes.stfc.ac.uk](http://host-172-16-112-243.nubes.stfc.ac.uk) 0 1 1 DinRW ├──▶ 6 [host-172-16-103-55.nubes.stfc.ac.uk](http://host-172-16-103-55.nubes.stfc.ac.uk) 0 1 1 DinRW └──▶ 9 [host-172-16-112-247.nubes.stfc.ac.uk](http://host-172-16-112-247.nubes.stfc.ac.uk) 0 1 1 DinRW eos fs ls ┌────────────────────────────────────┬────┬──────┬────────────────────────────────┬────────────────┬────────────────┬────────────┬──────────────┬────────────┬────────┬────────────────┐ │host │port│ id│ path│ schedgroup│ geotag│ boot│ configstatus│ drain│ active│ health│ └────────────────────────────────────┴────┴──────┴────────────────────────────────┴────────────────┴────────────────┴────────────┴──────────────┴────────────┴────────┴────────────────┘ [host-172-16-112-243.nubes.stfc.ac.uk](http://host-172-16-112-243.nubes.stfc.ac.uk) 1095 1 /data01 default.0 rack1 booted off nodrain online N/A [host-172-16-112-243.nubes.stfc.ac.uk](http://host-172-16-112-243.nubes.stfc.ac.uk) 1095 2 /data02 default.1 rack1 booted off nodrain online N/A [host-172-16-112-243.nubes.stfc.ac.uk](http://host-172-16-112-243.nubes.stfc.ac.uk) 1095 3 /data03 default.2 rack1 booted off nodrain online N/A [host-172-16-103-55.nubes.stfc.ac.uk](http://host-172-16-103-55.nubes.stfc.ac.uk) 1095 4 /data01 default.0 rack1 booted rw nodrain online N/A [host-172-16-103-55.nubes.stfc.ac.uk](http://host-172-16-103-55.nubes.stfc.ac.uk) 1095 5 /data02 default.1 rack1 booted rw nodrain online N/A [host-172-16-103-55.nubes.stfc.ac.uk](http://host-172-16-103-55.nubes.stfc.ac.uk) 1095 6 /data03 default.2 rack1 booted rw nodrain online N/A [host-172-16-112-247.nubes.stfc.ac.uk](http://host-172-16-112-247.nubes.stfc.ac.uk) 1095 7 /data01 default.0 rack1 booted rw nodrain online N/A [host-172-16-112-247.nubes.stfc.ac.uk](http://host-172-16-112-247.nubes.stfc.ac.uk) 1095 8 /data02 default.1 rack1 booted rw nodrain online N/A [host-172-16-112-247.nubes.stfc.ac.uk](http://host-172-16-112-247.nubes.stfc.ac.uk) 1095 9 /data03 default.2 rack1 booted rw nodrain online N/A ---
