Hi I have successfully created a repository for snapshots -

> {  
> "my\_fs\_backup" : {  
> "type" : "fs",  
> "settings" : {  
> "compress" : "true",  
> "chunk\_size" : "10m",  
> "location" : "/mount/backups/my\_backup"  
> }  
> }  
> }

While checking flow for the same , i found this -

> write fd=175(/mount/backups/my\_backup/tests-lmIg4vpAQcmbNX9g7k630w/master.dat-temp)  
> write res=22 data=lmIg4vpAQcmbNX9g7k630w

Can anyone suggest what exactly is happening here , is it verifying the blob container created ??

Please format your code, logs or configuration files using `</>` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable.

> is it verifying the blob container created ??

yes. The master node writes this file. All other data nodes are making sure they can read it.

Thanks David for the information . Please confirm my understanding stated below -

Is this is where the data nodes access it ???  
`11865 11:18:04.693719497 1 java (18817) > write fd=175(<f>/mount/backups/my_backup/tests-lmIg4vpAQcmbNX9g7k630w/data-r_92eAj3T_yeM_hektIGaA.dat) size=22 11866 11:18:04.693729718 1 java (18817) < write res=22 data=lmIg4vpAQcmbNX9g7k630w`

and here the master node verifies the blob container  
`10724 11:18:04.652241228 1 java (18817) < lstat res=0 path=/mount/backups/my_backup/tests-lmIg4vpAQcmbNX9g7k630w 10725 11:18:04.652251423 1 java (18817) > access mode=0(F_OK) 10726 11:18:04.652253456 1 java (18817) < access res=-2(ENOENT) name=/mount/backups/my_backup/tests-lmIg4vpAQcmbNX9g7k630w/master.dat-temp 10727 11:18:04.652307470 1 java (18817) > open 10728 11:18:04.652458262 1 java (18817) < open fd=175(<f>/mount/backups/my_backup/tests-lmIg4vpAQcmbNX9g7k630w/master.dat-temp) name=/mount/backups/my_backup/tests-lmIg4vpAQcmbNX9g7k630w/master.dat-temp flags=38(O_EXCL|O_CREAT|O_WRONLY) mode=0666 10729 11:18:04.652505467 1 java (18817) > write fd=175(<f>/mount/backups/my_backup/tests-lmIg4vpAQcmbNX9g7k630w/master.dat-temp) size=22 10730 11:18:04.652514168 1 java (18817) < write res=22 data=lmIg4vpAQcmbNX9g7k630w 10731 11:18:04.652523403 1 java (18817) > close fd=175(<f>/mount/backups/my_backup/tests-lmIg4vpAQcmbNX9g7k630w/master.dat-temp) 10732 11:18:04.652523940 1 java (18817) < close res=0`
