Permintaan untuk melaporkan alokasi ruang disk dan ruang yang digunakan

Kami menggunakan total 6 basis data untuk suatu aplikasi, dan kami hanya dapat berbagi ruang 4TB di antara semua 6 basis data tumbuh otomatis (melalui penyimpanan SAN).

Saya ingin menulis kueri (laporan) untuk satu basis data yang menunjukkan atribut "Ruang yang dialokasikan saat ini" dan "Ruang kosong yang tersedia" di bawah opsi Tugas> Kecilkan> Basis Data di SQL Server Management Studio.

Lalu saya ingin mengonversi angka-angka itu menjadi TB dan totalkan setiap basis data untuk mendapatkan perkiraan kasar berapa banyak ruang yang tersisa. Bisakah bidang ini diakses melalui kueri T-SQL? Jika demikian, seperti apa tampilan kueri?

Berikut adalah kueri yang digunakan Management Studio untuk mengisi angka-angka itu:

SELECT
(SELECT SUM(CAST(df.size as float)) FROM sys.database_files AS df 
   WHERE df.type in ( 0, 2, 4 ) ) AS [DbSize],
SUM(a.total_pages) AS [SpaceUsed],
(SELECT SUM(CAST(df.size as float)) FROM sys.database_files AS df 
   WHERE df.type in (1, 3)) AS [LogSize]
FROM
sys.partitions p join sys.allocation_units a 
  on p.partition_id = a.container_id 
left join sys.internal_tables it 
  on p.object_id = it.object_id

Anda perlu melakukan matematika di sini seperti halnya Management Studio untuk mendapatkan angka yang sama. Juga, kiri bergabung sys.internal_tablestampaknya tidak berguna di terbaik. Jadi, sesuaikan kueri itu agar sesuai dengan output ideal Anda:

SELECT
(SELECT CONVERT(DECIMAL(18,2), SUM(CAST(df.size as float))*8/1024.0)
   FROM sys.database_files AS df 
   WHERE df.type in ( 0, 2, 4 ) ) AS [DbSize],
CONVERT(DECIMAL(18,2), SUM(a.total_pages)*8/1024.0) AS [SpaceUsed],
(SELECT CONVERT(DECIMAL(18,2), SUM(CAST(df.size as float))*8/1024.0)
   FROM sys.database_files AS df 
   WHERE df.type in (1, 3)) AS [LogSize]
FROM sys.partitions p join sys.allocation_units a 
  on p.partition_id = a.container_id;

Dengan pembaruan ini, dengan asumsi database Anda tidak berubah untuk sementara, itu akan menghasilkan:

753475.94    744030.07    2900.00

Melakukan beberapa matematika sederhana, dan mengisolasi hanya tiga angka yang Anda inginkan:

;WITH t(s) AS
(
  SELECT CONVERT(DECIMAL(18,2), SUM(size)*8/1024.0)
   FROM sys.database_files
   WHERE [type] % 2 = 0
), 
d(s) AS
(
  SELECT CONVERT(DECIMAL(18,2), SUM(total_pages)*8/1024.0)
   FROM sys.partitions AS p
   INNER JOIN sys.allocation_units AS a 
   ON p.[partition_id] = a.container_id
)
SELECT 
  Allocated_Space = t.s, 
  Available_Space = t.s - d.s,
  [Available_%] = CONVERT(DECIMAL(5,2), (t.s - d.s)*100.0/t.s)
FROM t CROSS APPLY d;

Kueri Aaron baik, tetapi sebagai alternatif, saya menggunakan kueri ini dari Permintaan DMV Glenn Berry
(Anda perlu mengubah matematika untuk TB):

-- Individual File Sizes and space available for current database
-- (Query 36) (File Sizes and Space)
SELECT f.name AS [File Name] , f.physical_name AS [Physical Name], 
CAST((f.size/128.0) AS DECIMAL(15,2)) AS [Total Size in MB],
CAST(f.size/128.0 - CAST(FILEPROPERTY(f.name, 'SpaceUsed') AS int)/128.0 AS DECIMAL(15,2)) 
AS [Available Space In MB], [file_id], fg.name AS [Filegroup Name]
FROM sys.database_files AS f WITH (NOLOCK) 
LEFT OUTER JOIN sys.data_spaces AS fg WITH (NOLOCK) 
ON f.data_space_id = fg.data_space_id OPTION (RECOMPILE);

Inilah beberapa SQL yang mungkin cocok untuk Anda.

Create Table #dbInfo (dId smallint, dbName sysname, gId smallint NULL, segName varchar(256) NULL, 
       filName varchar(520) NULL, sizeMg decimal(10,2) null, 
       usedMg decimal(10,2) null, freeMg decimal(10,2) null, 
       pcntUsed decimal(10,2) null, pcntFree decimal(10,2) null)
Declare @sSql varchar(1000)
Set @sSql = 'Use [?];
Insert #dbInfo (dId, dbName, gid, segName, filName, sizeMg, usedMg)
Select db_id(), db_name(), groupid, rtrim(name), filename, Cast(size/128.0 As Decimal(10,2)), 
Cast(Fileproperty(name, ''SpaceUsed'')/128.0 As Decimal(10,2))
From dbo.sysfiles Order By groupId Desc;'
Exec sp_MSforeachdb @sSql
Update #dbInfo Set
freeMg = sizeMg - usedMg,
pcntUsed = (usedMg/sizeMg)*100,
pcntFree = ((sizeMg-usedMg)/sizeMg)*100

select * from #dbInfo compute sum(sizeMG),  sum(FreeMg) 
drop table #dbInfo

Ini SQL lama tapi masih berfungsi. Suatu hari saya akan menulis ulang untuk menggunakan sys.database_files seperti jawaban dari Aaron.

Setelah mengerjakan pertanyaan serupa ( Mengukur Ukuran File Basis Data Benar Fisik ), saya pikir pertanyaan yang menampilkan ukuran file yang berbeda, dipisahkan, misalnya dengan log dan database, dan ukuran file pada disk akan lebih membantu bagi sebagian besar pengguna.

Ini termasuk ukuran file sistem dan berapa banyak ruang yang digunakan pada disk, serta ukuran file SQL, ruang SQL yang digunakan, dan dengan perluasan ruang bebas SQL juga. Ini termasuk path lengkap file yang sedang dievaluasi. Seorang pengguna perlu mengubah perhitungan untuk 'Size_On_Disk_Bytes' jika disk diformat menggunakan ukuran alokasi yang berbeda dari standar (4096 byte).

SELECT fg.data_space_id AS FGID,
   (f.file_id) AS File_Id,
   -- As provided by OP, size on disk in bytes.
   REPLACE(CONVERT(VARCHAR,CONVERT(MONEY, CAST(f.size AS FLOAT) * 8.00 * 1024), 1), '.00','') AS Size_On_Disk_Bytes,
   ROUND((CAST(f.size AS FLOAT) * 8.00/1024)/1024,3) AS Actual_File_Size,
   ROUND(CAST((f.size) AS FLOAT)/128,2) AS Reserved_MB,
   ROUND(CAST((FILEPROPERTY(f.name,'SpaceUsed')) AS FLOAT)/128,2) AS Used_MB,
   ROUND((CAST((f.size) AS FLOAT)/128)-(CAST((FILEPROPERTY(f.name,'SpaceUsed'))AS FLOAT)/128),2) AS Free_MB,
   f.name,
   f.physical_name
FROM sys.database_files f 
    LEFT JOIN sys.filegroups fg
    ON f.data_space_id = fg.data_space_id

Selain itu, kueri ini akan mengembalikan informasi tentang ruang pada drive volume yang menjadi tuan rumah file. Pengguna harus memiliki akses ke sys.master_files.

SELECT DISTINCT dovs.logical_volume_name AS LogicalName,
dovs.volume_mount_point AS Drive,
CONVERT(INT,dovs.available_bytes/1048576.0) AS FreeSpaceInMB
FROM sys.master_files mf
CROSS APPLY sys.dm_os_volume_stats(mf.database_id, mf.FILE_ID) dovs
ORDER BY FreeSpaceInMB ASC

Sesuatu yang saya kumpulkan. Anda PERLU POWERSHELL pada SQL Server Anda untuk menjalankan ini. Tidak yakin dengan versinya. Ini akan mengambil ukuran drive Anda dan melaporkan kembali ukuran file dan ruang kosong serta ruang drive gratis.

Ini bukan 100% asli dan bagian dari itu saya temukan di tempat lain di internet dan menyatukan semuanya. Itu adalah PITA untuk membuatnya agar sesuai dengan margin yang tepat sehingga Anda mungkin harus bermain dengan tanda kurung
