Title: Message Title

Martin Ewings created an issue   Facter / FACT-1814 Mountpoints Fact available space does not accurately reflect disk usage Issue Type: Bug Affects Versions: FACT 3.6.5 Assignee: Unassigned Attachments: output.txt Created: 2018/02/02 6:56 AM Priority: Normal Reporter: Martin Ewings PE 2017.2.2 ( facter 3.6.5) RHEL 6.8 The customer is using mountpoints.(parition).available_bytes in conditional logging to determine if software should be installed on a system during Puppet Runs. In testing it appears that there is around a 400mb discrepancy between what is reported by facter as available, and what is actually available, which is backed up by df -h. In a test where by continual facter outputs and df outputs where collected during a large file transfer to the target partition, both facter and df -h tracked upwards in consumed disk space, but never agreed with each other, full attachments below, however a snippet can be seen here: ----facter---- 2568753152 2.39 GiB 58.62% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 3.4G 2.1G 62% /var ----facter---- 2568753152 2.39 GiB 58.62% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 3.4G 2.1G 62% /var ----facter---- 846790656 773.65 MiB 87.52% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 5.1G 431M 93% /var ----facter---- 415592448 396.34 MiB 93.30% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 5.4G 90M 99% /var ----facter---- 415592448 396.34 MiB 93.30% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 5.4G 90M 99% /var ----facter---- 415592448 396.34 MiB 93.30% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 5.4G 90M 99% /var ----facter---- 421269504 401.75 MiB 93.21% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 5.4G 95M 99% /var ----facter---- 421269504 401.75 MiB 93.21% ----system---- Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg_root-lv_var ext4 5.8G 5.4G 95M 99% /var It could be that facter is failing to take into consideration the blocksize for the partition, in which case i have provided the output below: blockdev --getbsz /dev/mapper/vg_root-lv_var 4096 Add Comment   This message was sent by Atlassian JIRA (v7.0.2#70111-sha1:88534db) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.
