From 3afd86683b7324c9fec94ca2c35b64ac72ab523f Mon Sep 17 00:00:00 2001 From: Goffredo Baroncelli Date: Mon, 8 Jun 2015 13:00:50 +0200 Subject: btrfs-progs: mkfs: print the summary This patch prints the summary of the filesystem after the creation. The main fileds printed are: - devices list with their uuid, devid, path and size - raid profile (dup,single,raid0...) - leafsize/nodesize/sectorsize - filesystem features (raid56, extref, mixed-bg) - chunk size and type If the '-v' switched is passed, the output is more verbose; if the '-q' switched is passed, only the errors are printed. Below an example: BTRFS filesystem summary: Label: btrfs-test UUID: 14ae8a88-98ac-4f22-8441-79f76ec622f7 Node size: 4096 Leaf size: 4096 Sector size: 4096 Initial chunks: Data+Metadata: 9.01GiB System: 18.06MiB Metadata profile: RAID5 Data profile: RAID5 Mixed mode: YES SSD detected: NO Incompat features: mixed-bg, extref, raid56 Number of devices: 10 UUID ID SIZE PATH ------------------------------------ -- --------- ----------- df1c7f50-1980-4da2-8bc9-7ee6ffb0b554 1 50.00GiB /dev/vdb 32c808a0-cd7b-4497-a2c0-1d77a9854af9 2 50.00GiB /dev/vdc 3159782e-d108-40bc-9e15-090ecac160b4 3 50.00GiB /dev/vdd db7eaf0c-beb8-4093-a9d0-b9c25c146305 4 50.00GiB /dev/vde c367ca04-1f71-49c0-a331-11fc0b87e9fc 5 50.00GiB /dev/vdf e9b73c86-4058-4b3a-90ac-18741a276e70 6 50.00GiB /dev/vdg c4298b7a-ad41-4690-bf10-bf748b319413 7 50.00GiB /dev/vdh 1cf048c8-af8a-4225-b09a-5d12e9b217fa 8 2.00GiB /dev/vdi 7e157869-768a-4725-bad5-82e6bd05fd17 9 2.00GiB /dev/vdj 2c9431ac-c7f0-45a5-8529-cef8cf6e4033 10 2.00GiB /dev/vdk Total devices size: 356.01GiB Signed-off-by: Goffredo Baroncelli Signed-off-by: David Sterba --- mkfs.c | 79 +++++++++++++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 66 insertions(+), 13 deletions(-) (limited to 'mkfs.c') diff --git a/mkfs.c b/mkfs.c index 10481b8..6cff69f 100644 --- a/mkfs.c +++ b/mkfs.c @@ -1132,13 +1132,43 @@ static int is_ssd(const char *file) return !atoi((const char *)&rotational); } +static void list_all_devices(struct btrfs_root *root) +{ + struct btrfs_fs_devices *fs_devices; + struct btrfs_device *device; + int number_of_devices = 0; + u64 total_block_count = 0; + + fs_devices = root->fs_info->fs_devices; + + list_for_each_entry(device, &fs_devices->devices, dev_list) + number_of_devices++; + + printf(" Number of devices:\t%d\n", number_of_devices); + printf(" UUID ID SIZE PATH\n"); + printf(" ------------------------------------ -- --------- -----------\n"); + list_for_each_entry_reverse(device, &fs_devices->devices, dev_list) { + char dev_uuid[BTRFS_UUID_UNPARSED_SIZE]; + + uuid_unparse(device->uuid, dev_uuid); + printf(" %s %3llu %10s %s\n", + dev_uuid, device->devid, + pretty_size(device->total_bytes), + device->name); + total_block_count += device->total_bytes; + } + + printf("\n"); + printf(" Total devices size: %10s\n", + pretty_size(total_block_count)); +} + int main(int ac, char **av) { char *file; struct btrfs_root *root; struct btrfs_trans_handle *trans; char *label = NULL; - char *first_file; u64 block_count = 0; u64 dev_block_count = 0; u64 blocks[7]; @@ -1423,7 +1453,6 @@ int main(int ac, char **av) strerror(errno)); exit(1); } - first_file = file; ret = btrfs_prepare_device(fd, file, zero_end, &dev_block_count, block_count, &mixed, discard); if (ret) { @@ -1441,7 +1470,6 @@ int main(int ac, char **av) exit(1); } - first_file = file; source_dir_size = size_sourcedir(source_dir, sectorsize, &num_of_meta_chunks, &size_of_data); if(block_count < source_dir_size) @@ -1485,9 +1513,6 @@ int main(int ac, char **av) features |= BTRFS_FEATURE_INCOMPAT_RAID56; } - if (verbose) - btrfs_process_fs_features(features); - ret = make_btrfs(fd, file, label, fs_uuid, blocks, dev_block_count, nodesize, sectorsize, stripesize, features); if (ret) { @@ -1576,13 +1601,6 @@ raid_groups: ret = create_data_reloc_tree(trans, root); BUG_ON(ret); - if (verbose) { - printf( - "fs created label %s on %s\n\tnodesize %u leafsize %u sectorsize %u size %s\n", - label, first_file, nodesize, nodesize, sectorsize, - pretty_size(btrfs_super_total_bytes(root->fs_info->super_copy))); - } - btrfs_commit_transaction(trans, root); if (source_dir_set) { @@ -1597,6 +1615,41 @@ raid_groups: BUG_ON(ret); } + if (verbose) { + char features_buf[64]; + + printf("BTRFS filesystem summary:\n"); + printf(" Label:\t\t%s\n", label); + printf(" UUID:\t\t\t%s\n", fs_uuid); + printf("\n"); + + printf(" Node size:\t\t%u\n", nodesize); + printf(" Sector size:\t\t%u\n", sectorsize); + printf(" Initial chunks:\n"); + if (allocation.data) + printf(" Data:\t\t%s\n", + pretty_size(allocation.data)); + if (allocation.metadata) + printf(" Metadata:\t\t%s\n", + pretty_size(allocation.metadata)); + if (allocation.mixed) + printf(" Data+Metadata:\t%s\n", + pretty_size(allocation.mixed)); + printf(" System:\t\t%s\n", + pretty_size(allocation.system)); + printf(" Metadata profile:\t%s\n", + btrfs_group_profile_str(metadata_profile)); + printf(" Data profile:\t\t%s\n", + btrfs_group_profile_str(data_profile)); + printf(" Mixed mode:\t\t%s\n", mixed ?
