Subject: [PATCH v4 3/4] nfs05.sh: Lower down the default values
Date: Fri, 28 Apr 2023 18:00:37 +0200	[thread overview]
Message-ID: <20230428160038.3534905-4-pvorel@suse.cz> (raw)
In-Reply-To: <20230428160038.3534905-1-pvorel@suse.cz>

nfs05_make_tree.c runs make which needs on Btrfs quite a lot of
temporary space. This is a preparation for the next commit which
start using all filesystems via TST_ALL_FILESYSTEMS=1. Currently we use
300 MB, which was not enough for Btrfs:

Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/loop0     btrfs     300M   62M   20K 100% /tmp/LTP_nfs05.Vau10kcszO/mntpoint

After lowering the default values 96% (58M) is being used.

Proper solution would be to detect available size in nfs05_make_tree.c
and lower down values based on free space.
