See my hosting is under Digital Ocean with 320 SSD capacity. I was able to upload the files without any issues earlier. After the 320 GB capacity storage is full, I had to buy a new volume with an SSD capacity of 200 GB. I attached the SSD to my server correctly. I verified it from the Digital ocean. After attaching, I tried uploading the files which are more than 200MB in size, but not uploadable. It shows as the file is uploading, but it’s not writing to my new volume. Instead, it is writing to my old SSD which is already full. Due to which the upload fails.
I hope this is clear now.
