hi, all

# Question first:

first times, add parameters in the ceph.conf , like this: 
osd mkfs options xfs = "-f -i size=2048”

after execute:  
# pveceph createmon

the parameter is changed. like:
osd mkfs options xfs = "-f -i size = 2048”

both sides of the '='  with have the APACE. 

when add the osd will be error, like:
order to align on 2048-sector boundaries.
The operation has completed successfully.
-i size option requires a value
Usage: mkfs.xfs
/* blocksize */	[-b log=n|size=num]
/* data subvol */	[-d agcount=n,agsize=n,file,name=xxx,size=num,
/* inode size */	[-i log=n|perblock=n|size=num,maxpct=n,attr=0|1|2,
/* log subvol */	[-l agnum=n,internal,size=num,logdev=xxx,version=n
/* label */	[-L label (maximum 12 characters)]
/* naming */	[-n log=n|size=num,version=2|ci]
/* prototype file */	[-p fname]
/* quiet */	[-q]
/* realtime subvol */	[-r extsize=num,size=num,rtdev=xxx]
/* sectorsize */	[-s log=n|size=num]
/* version */	[-V]
<devicename> is required unless -d name=xxx is given.
<num> is xxx (bytes), xxxs (sectors), xxxb (fs blocks), xxxk (xxx KiB),
xxxm (xxx MiB), xxxg (xxx GiB), xxxt (xxx TiB) or xxxp (xxx PiB).
<value> is xxx (512 byte blocks).
ceph-disk: Error: Command '['/sbin/mkfs', '-t', 'xfs', '-f', '-i', 'size', '=', '2048', '-f', '--', '/dev/sdb1']' returned non-zero exit status 1

maybe this is the CEPH’s mistake,

but the PVE maybe can keep the parameters without change?

# Question two:
the /etc/ceph/ceph.conf will be changed, insteed of the symlink from /etc/pve/ceph.conf.

# ls -l /etc/ceph/ceph.conf 
lrwxrwxrwx 1 root root 18 Aug 31 13:55 /etc/ceph/ceph.conf -> /etc/pve/ceph.conf

changed to: 
# ls -l /etc/ceph/ceph.conf
-rw-r----- 1 root www-data 2082 Aug  7 13:54 /etc/ceph/ceph.conf

and One more file will be appear:
# ls -l /etc/ceph/ceph.conf.orig 
-rw-r----- 1 root root 2082 Aug 31 14:30 /etc/ceph/ceph.conf.orig

this question I have does’t know what caused.

so, about this two question, somebody can help me?

thanks a lots.
