Dear Maintainer,
a monitoring script that uses "lsblk -JO" fails, because the produced
json output is invalid.
a shorter output "lsblk -J -o zone-app" (just an example field, others are also
affected)
also produces invalid json:
~~~
lsblk -J -o zone-app /dev/dm-0
{
"blockdevices": [
{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
},{
"zone-app": 0B
}
]
}
~~~
Other Fields put the 0B into quotation marks
~~~
lsblk -JO|grep -Eo '["][^"]*["][:].*0B.*[,]'|sort -u
"disc-gran": "0B",
"disc-max": "0B",
"wsame": "0B",
"zone-app": 0B,
"zone-sz": 0B,
"zone-wgran": 0B,
~~~
fields
disc-gran, disc-max and wssam do quote,
zone-ap, zone-sz and zone-wgran do not quote.
as a test "json_pp" from the package "perl"
"lsblk -JO|json_pp" prints an error message
