Currently, I got one CentOS in virtual box with openstack swift running which is installed by SAIO.
Question: Data would not stored in the node which I mount nfs.
For example, I create a container by curl, the output returns 201. But there is no data in the mounted directory. I refer to file /var/log/swift/proxy.error, and it shows
Error Insufficient storage balabala...
Would anyone help figure why this happens and how to fix it?
Thanks in advance!
Sure, there are some logs about the mounted node. By following the SAIO guide, the configurations remain almost the same except the ${USER}. I use 'osddev' for the user name and group name.
/dev/sdb1 on /mnt/sdb1 type xfs (rw,noatime,nodiratime,seclabel,attr2,nobarrier,inode64,logbufs=8,noquota)
And I got 4 directories under /mnt/sdb1 named 1, 2, 3 and 4 respectively. I mounted nfs on the directory '2',
I mount like this:
mount.nfs 192.168.0.1:/mnt/path/to/mount /mnt/sdb1/2
and the output of command 'mount' is like
192.168.0.1:/mnt/path/to/mount on /mnt/sdb1/2 type nfs4(rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=...,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.0.2,local_lock=none,addr=192.168.0.1)
The structure of the folder of 'mnt' is like this:
/mnt/sdb1 /1 /node /sdb1 /accounts /containers /objects /tmp /2 /node /sdb2 /containers /tmp /3 /node /sdb3 /accounts /containers /objects /tmp /4 /node /sdb4 /accounts /containers /objects /tmp
When the mount was done, I tried to create a new container, and it returned 201 created, and there was a db file name '48ce59400b16f806fe2fee7e40e236as.db' and another file named '48ce59400b16f806fe2fee7e40e236as.db.pending' under the directory /mnt/sdb1/2/node/sdb2/containers/291/6ab/48ce59400b16f806fe2fee7e40e236as which was the same as other directoies under /mnt/sdb1.
When I tried to create a new object, there was 'objects' directory under /mnt/sdb1/2/node/sdb1. But in other directories like /mnt/sdb1/1 or /mnt/sdb1/3, the 'objects' directory existed.
So I checked out the error log under /var/log/swift. And I found that in logs 'proxy.error' and 'storage2.error', there were some errors, I'll list them below:

So far, I realized that nfs does not support xattr. Would that caused the issue?
What I want to do is use swift-on-file to store data in the mounted directory(by nfs) like /mnt/sdb1/2.
