We ran out of disk on our solr instance. However even after cleaning up the

If the files you deleted to free space were Solr indexes, then they were
still held open by Solr.
Most operating systems other than Windows will let you delete files that
are open, but the space for those files is not actually freed until they
are closed, which may not happen until the program stops. Restarting
Solr would close those files, allowing the OS to free the space.

Windows will refuse to let you delete files if they are open.
General disk requirement for any Lucene-based software (which includes
Solr): Make sure you have enough space available for your indexes to
triple in size temporarily. In most cases, the possible size increase
will only be double, but there is a specific scenario that can lead to
the index reaching triple size, so we always recommend triple.
